Coherence

Estimate the magnitude squared coherence using Welch’s method. 4-mics-linear-array-kit coherence
Note: 'CO 1-2' means the coherence between channel 1 and channel 2.

# How to get the coherence of the captured audio(a.wav for example).
sudo apt install python-numpy python-scipy python-matplotlib
python tools/coherence.py a.wav

# Requirement of the input audio file:
- format: WAV(Microsoft) signed 16-bit PCM
- channels: >=2

uninstall seeed-voicecard

If you want to upgrade the driver , you need uninstall the driver first.

Technical support

For hardware testing purposes we made a Rasperry Pi OS 5.10.17-v7l+ 32-bit image with reSpeaker drivers pre-installed, which you can download by clicking on this link.

We provide official support for using reSpeaker with the following OS:

  • 32-bit Raspberry Pi OS
  • 64-bit Raspberry Pi OS

And following hardware platforms:

  • Raspberry Pi 3 (all models), Raspberry Pi 4 (all models)

Anything beyond the scope of official support is considered to be community supported. Support for other OS/hardware platforms can be added, provided MOQ requirements can be met.

If you have a technical problem when using reSpeaker with one of the officially supported platforms/OS, feel free to create an issue on Github. For general questions or suggestions, please use Seeed forum.
