## Installation
|
||
|
|
|
||
|
|
* Plug Audio+ firmly on top of your Raspberry Pi GPIO and turn on your Pi
|
||
|
|
|
||
|
|
* Open a terminal and type the following to download and run the installer:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo wget -O mic mic.raspiaudio.com
|
||
|
|
|
||
|
|
sudo bash mic
|
||
|
|
```
|
||
|
|
* Say yes to reboot
|
||
|
|
* On the next reboot you must run the test to finish the installation (it is an ALSA oddness):
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo wget -O test test.raspiaudio.com
|
||
|
|
|
||
|
|
sudo bash test
|
||
|
|
```
|
||
|
|
|
||
|
|
* Push the onboard button, you should hear "Front Left" "Front Right" then the recorded sequence by the microphone.
|
||
|
|
|
||
|
|
* If the volume is too low you can adjust the gain of the microphone by rebooting and typing the following into a terminal:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
alsamixer
|
||
|
|
```
|
||
