commit 3653480c68120dc16ebfeb80e529200dbbd98f92

ASoC: soc-dai.h: cleanup Playback/Capture data for snd_soc_dai
Current snd_soc_dai has data for Playback/Capture, but it is very
random. Someone is array (A), someone is playback/capture (B),
and someone is tx/rx (C);
struct snd_soc_dai {
...
(A) unsigned int stream_active[SNDRV_PCM_STREAM_LAST + 1];
(B) struct snd_soc_dapm_widget *playback_widget;
(B) struct snd_soc_dapm_widget *capture_widget;
(B) void *playback_dma_data;
(B) void *capture_dma_data;
...
(C) unsigned int tx_mask;
(C) unsigned int rx_mask;
};
Because of it, the code was very complicated.
This patch creates new data structure to merge these into one,
and tidyup the code.

Coherence
Estimate the magnitude squared coherence using Welch’s method.
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.
pi@raspberrypi:~/seeed-voicecard $ sudo ./uninstall.sh

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.
