# seeed-voicecard # seeed-voicecard-rockpi-armbian
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 ### Install seeed-voicecard
Get the seeed voice card source code and install all linux kernel drivers Get the seeed voice card source code and install all linux kernel drivers
```bash ```bash
git clone https://github.com/respeaker/seeed-voicecard git clone https://github.com/respeaker/seeed-voicecard
cd seeed-voicecard cd seeed-voicecard
sudo ./install.sh sudo ./install_arm64.sh
sudo reboot sudo reboot
``` ```
**Note** If you have 64-bit version of Rasperry Pi OS, use install_arm64.sh script for driver installation.
## ReSpeaker Documentation ## ReSpeaker Documentation
Up to date documentation for reSpeaker products can be found in [Seeed Studio Wiki](https://wiki.seeedstudio.com/ReSpeaker/)! See [Original seeed-voicecard](https://github.com/respeaker/seeed-voicecard) for additional information.
![](https://files.seeedstudio.com/wiki/ReSpeakerProductGuide/img/Raspberry_Pi_Mic_Array_Solutions.png)
### Coherence
Estimate the magnitude squared coherence using Welch’s method.
![4-mics-linear-array-kit coherence](https://user-images.githubusercontent.com/3901856/37277486-beb1dd96-261f-11e8-898b-84405bfc7cea.png)
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).
