We provide tools to dump audio data from topic `/apollo/sensor/microphone` to wave files.
### How
To do so,
1. Change `WAV_SAVING_PATH` in `audiosaver.py` to the directory for saving wave files, which is default to `/tmp`.
2. Run command `python3 audiosaver.py` to start to listen to audio data from the topic `/apollo/sensor/microphone` (while playing a record, etc.).
3. Terminate the program with `Ctrl + C` when you want to stop listening & save data to wave files under the target directory.
By default, there are 6 audio channels, so 6 files will be generated -- one for each audio channel. For information of the audio channel, refer to [Microphone](../../drivers/microphone/README.md) and [Microphone Configuration](../../drivers/microphone/conf/respeaker.pb.txt).
