### Coherence
|
||
|
||
Estimate the magnitude squared coherence using Welch’s method.
|
||
|
||
Note: 'CO 1-2' means the coherence between channel 1 and channel 2.
|
||
|
||
```bash
|
||
# 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
|
||
```
|
||
|
||

### 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](https://files.seeedstudio.com/linux/Raspberry%20Pi%204%20reSpeaker/2021-05-07-raspios-buster-armhf-lite-respeaker.img.xz).
|
||
|
||
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](https://forum.seeedstudio.com/c/products/respeaker/15).
