# What is audio pong?
This is a small nodejs server for your raspberry 3.
It serves a sound board to your phone, you click on a tile to play a sound on you phone and another sound will be played on the raspberry, making a fun effect like ping pong, reload and fire, smash and cry...
## Install on a raspberry 3
on your raspberry, install these libs for audio and nodejs
```
sudo apt-get update
# install nodejs
sudo apt-get install -y npm wget
sudo npm install -g n
sudo n latest
# setup audio
sudo apt-get install -y mpg321
```
then start the server (you can add [use these techniques to start the server on startup boot](http://raspberrywebserver.com/serveradmin/run-a-script-on-start-up.html))
```
$ npm i
$ npm start
```
then open `http://[raspberry IP]:8080` on your phone and enjoy the sound on the 2 devices
> tip: you may need to type `amixer cset numid=3 1` to force the raspberry to output audio on the "analog" output instead of hdmi
> tip: you can use this command to test your audio: `speaker-test -t sine -f 440 -c 2 -s 1`
## add sounds to the board
You will need 2 mp3 sounds, one for ping (played by the phone) and one for pong (played by the raspberry)
* add 2 sounds to the [`sounds/` folder](./sounds)
* add an entry in [audio.json](./audio.json)
* change the number of sounds in [`index.html` on this line here](https://github.com/lexoyo/audio-pong/blob/master/index.html#L29)
Feel free to contribute your sounds here, only creative commons one please (home made or not) ;)
