The drivers for [ReSpeaker Mic Hat](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT-p-2874.html), [ReSpeaker 4 Mic Array](https://www.seeedstudio.com/ReSpeaker-4-Mic-Array-for-Raspberry-Pi-p-2941.html), [6-Mics Circular Array Kit](), and [4-Mics Linear Array Kit]() for Raspberry Pi.
|
||||
This is a fork of https://github.com/respeaker/seeed-voicecard to support Armbian runnong on RockPi 4b.
|
||||
|
||||
Requirements:
|
||||
- Armbian RockPi linux version 21.05.4 (linux kernel 5.10.43-rockchip64)
|
||||
|
||||
Note that only the ReSpeaker Mic Hat (2-mic) is correct at this stage.
|
||||
|
||||
The original provides drivers for [ReSpeaker Mic Hat](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT-p-2874.html), [ReSpeaker 4 Mic Array](https://www.seeedstudio.com/ReSpeaker-4-Mic-Array-for-Raspberry-Pi-p-2941.html), [6-Mics Circular Array Kit](), and [4-Mics Linear Array Kit]() for Raspberry Pi.
|
||||
|
||||
Only the driver for the ReSpeaker Mic Hat has been ported correctly at this stage.
|
||||
|
||||
### Install seeed-voicecard
|
||||
Get the seeed voice card source code and install all linux kernel drivers
|
||||
```bash
|
||||
git clone https://github.com/respeaker/seeed-voicecard
|
||||
cd seeed-voicecard
|
||||
sudo ./install.sh
|
||||
sudo ./install_arm64.sh
|
||||
sudo reboot
|
||||
```
|
||||
|
||||
**Note** If you have 64-bit version of Rasperry Pi OS, use install_arm64.sh script for driver installation.
|
||||
|
||||
## ReSpeaker Documentation
|
||||
|
||||
Up to date documentation for reSpeaker products can be found in [Seeed Studio Wiki](https://wiki.seeedstudio.com/ReSpeaker/)!
|
||||
|
||||
|
||||
|
||||
### 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
|
||||
```
|
||||
|
||||
### uninstall seeed-voicecard
|
||||
If you want to upgrade the driver , you need uninstall the driver first.
|
||||
|
||||
```
|
||||
pi@raspberrypi:~/seeed-voicecard $ sudo ./uninstall.sh
|
||||
...
|
||||
------------------------------------------------------
|
||||
Please reboot your raspberry pi to apply all settings
|
||||
Thank you!
|
||||
------------------------------------------------------
|
||||
```
|
||||
|
||||
Enjoy !
|
||||
|
||||
### 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 (experimental support)
|
||||
|
||||
And following hardware platforms:
|
||||
- Raspberry Pi 3 (all models), Raspberry Pi 4 (all models), Raspberry Pi Zero and Zero W
|
||||
|
||||
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).
|
||||
|
||||
|
||||
See [Original seeed-voicecard](https://github.com/respeaker/seeed-voicecard) for additional information.
