Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|
     |---|---|
     |![](https://user-images.githubusercontent.com/19769486/86824253-d9e6df80-c0c8-11ea-8946-ca1367c1b1b0.png)|![](https://user-images.githubusercontent.com/19769486/86824246-d81d1c00-c0c8-11ea-8c13-dc9660e89ea0.png)|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|

Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|

Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|

Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|
     |---|---|
     |![](https://user-images.githubusercontent.com/19769486/86824253-d9e6df80-c0c8-11ea-8946-ca1367c1b1b0.png)|![](https://user-images.githubusercontent.com/19769486/86824246-d81d1c00-c0c8-11ea-8c13-dc9660e89ea0.png)|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|

Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|
     |---|---|
     |![](https://user-images.githubusercontent.com/19769486/86824253-d9e6df80-c0c8-11ea-8946-ca1367c1b1b0.png)|![](https://user-images.githubusercontent.com/19769486/86824246-d81d1c00-c0c8-11ea-8c13-dc9660e89ea0.png)|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|

Sound Classification

ROS package to classify sound stream.

Contents

Setup

  1. Install ROS. Available OS:
    • Ubuntu 16.04 (?)
    • Ubuntu 18.04
  2. Create workspace
    mkdir ~/sound_classification_ws/src -p
    cd ~/sound_classification_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_recognition.git
    rosdep install --from-paths . --ignore-src -y -r
    cd ..
    catkin build sound_classification
    source ~/sound_classification_ws/devel/setup.bash
  1. Install other packages.

Usage

  1. Check and specify your microphone parameters.
    • In particular, device, n_channel, bitdepth and mic_sampling_rate need to be known.
    • The example bash commands to get these params are below:
        # For device. In this example, card 0 and device 0, so device:="hw:0,0"
        $ arecord -l
        \**** List of CAPTURE Hardware Devices ****
        card 0: PCH [HDA Intel PCH], device 0: ALC293 Analog [ALC293 Analog]
        Subdevices: 1/1
        Subdevice #0: subdevice #0
        

        # For n_channel, bitdepth and sample_rate,
        # Note that sources means input (e.g. microphone) and sinks means output (e.g. speaker)
        $ pactl list short sources
        1       alsa_input.pci-0000_00_1f.3.analog-stereo       module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
        

- Pass these params to each launch file as arguments when launching (e.g., `device:=hw:0,0 n_channel:=2 bitdepth:=16 mic_sampling_rate:=44100`).
- If you use `/audio` topic from other computer and do not want to publish `/audio`, set `use_microphone:=false` at each launch file when launching.
  1. Save environmental noise to train_data/noise.npy.
    • By subtracting noise, spectrograms become clear.
    • During this script, you must not give any sound to the sensor.
    • You should update noise data everytime before sound recognition, because environmental sound differs everytime.
    • 30 noise samples are enough.
        $ roslaunch sound_classification save_noise.launch
  1. Publish audio -> spectrum -> spectrogram topics.
    • You can set the max/min frequency to be included in the spectrum by high_cut_freq/low_cut_freq args in audio_to_spectrogram.launch.
    • If gui:=true, spectrum and spectrogram are visualized.
        $ roslaunch sound_classification audio_to_spectrogram.launch gui:=true
        

 - Here is an example spectrogram at quiet environment.
     - Horiozntal axis is time [Hz]
     - Vertical axis is frequency [Hz]

     |Spectrogram w/o noise subtraction|Spectrogram w/ noise subtraction|
     |---|---|
     |![](https://user-images.githubusercontent.com/19769486/86824253-d9e6df80-c0c8-11ea-8946-ca1367c1b1b0.png)|![](https://user-images.githubusercontent.com/19769486/86824246-d81d1c00-c0c8-11ea-8c13-dc9660e89ea0.png)|

  1. Collect spectrogram you would like to classify.

    • When the volume exceeds the threshold, save the spectrogram at train_data/original_spectrogram/TARGET_CLASS.
    • You can use rosbag and stream as sound sources.
    1. Rosbag version (Recommended)
      • I recommend to use rosbag to collect spectrograms. The rosbag makes it easy to use save_sound.launch with several parameters.
      • In target_class:=TARGET_CLASS, you can set the class name of your target sound.
      • By using use_rosbag:=true and filename:=PATH_TO_ROSBAG, you can save spectrograms from rosbag.
      • By default, rosbag is paused at first. Press ‘Space’ key on terminal to start playing rosbag. When rosbag ends, press ‘Ctrl-c’ to terminate.
      • The newly saved spectrograms are appended to existing spectrograms.
      • You can change threshold of sound saving by threshold:=xxx. The smaller the value is, the more easily sound is saved.
            # Save audio to rosbag
            $ roslaunch sound_classification record_audio_rosbag.launch filename:=PATH_TO_ROSBAG
            

            # play rosbag and collecting data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=TARGET_CLASS threshold:=0.5
            

    - By setting `threshold:=0` and `save_when_sound:=false`, you can collect spectrogram of "no sound".

            # play rosbag and collecting no-sound data
            $ export ROS_MASTER_URI=http://localhost:11311
            $ roslaunch sound_classification save_sound.launch use_rosbag:=true \
              filename:=PATH_TO_ROSBAG target_class:=no_sound threshold:=0 save_when_sound:=false
            

1. Stream version (Not Recommended)
    - You can collect spectrogram directly from audio topic stream.
    - Do not use `use_rosbag:=true`. The other args are the same as the rosbag version. Please see above.

            $ roslaunch sound_classification save_sound.launch \
            save_when_sound:=true target_class:=TARGET_CLASS threshold:=0.5 save_data_rate:=5
  1. Create dateaset for chainer from saved spectrograms.
    • Some data augmentation is executed.
    • --number 30 means to use maximum 30 images for each class in dataset.
        $ rosrun sound_classification create_dataset.py --number 30
  1. Visualize dataset.
    • You can use train arg for train dataset (augmented dataset), test arg for test dataset.
    • The spectrograms in the dataset are visualized in random order.
        $ rosrun sound_classification visualize_dataset.py test # train/test
  1. Train with dataset.
    • Default model is NIN (Recommended).
    • If you use vgg16, pretrained weights of VGG16 is downloaded to scripts/VGG_ILSVRC_16_layers.npz at the first time you run this script.
        $ rosrun sound_classification train.py --epoch 30
  1. Classify sounds.
    • It takes a few seconds for the neural network weights to be loaded.
    • use_rosbag:=true and filename:=PATH_TO_ROSBAG is available if you classify sound with rosbag.
        $ roslaunch sound_classification classify_sound.launch
        

- You can fix class names' color in classification result image by specifying order of class names like below:

        <rosparam>
          target_names: [none, other, chip_bag]
        </rosparam>
        

- Example classification result:
    |no_sound|applause|voice|
    |---|---|---|
