Sound Recording

This example demonstrates how to record audio from Reachy Mini's microphone array and save it to a WAV file. The script records for 5 seconds and saves the audio to recorded_audio.wav.

How it works:

1. Starts audio recording using start_recording()
2. Continuously retrieves audio samples using get_audio_sample()
3. Collects samples until the desired duration is reached
4. Stops recording and concatenates all samples
5. Saves the audio data to a WAV file using soundfile

Features:

• Configurable recording duration (default: 5 seconds)
• Automatic sample rate detection
• Timeout protection to prevent infinite loops
• Support for different media backends

Usage:

python sound_record.py --backend [default_no_video|gstreamer_no_video|webrtc]

The recorded audio will be saved to recorded_audio.wav in the current directory.
