A simple WAV/MP3 recorder on a raspberry pi with hifiberry dac+ adc and a harddrive to record and share data on a local network with only one click
git clone git@github.com:interym/pi-recorder.git $HOME/pi-recorder
cd $HOME/pi-recorder
./systemd/install.sh
./systemd/start.sh
To auto-start at boot, enable user lingering for your user.
loginctl enable-linger your-username
Note: Currently, the sytemd scripts assume that a checkout resides in $HOME/pi-recorder
The systemd units that are installed above do nothing but execute two commands:
-
Start the GPIO-controlled recorder:
./gpio-recorder.py -
Start the web ui:
node webui/server.js
A Python script uses RPi.GPIO to listen on a button, start/stop recording (with arecord), and let a LED blink. It places recorded WAV files in a folder Recordings.
A NodeJS server uses Express to serve the recorded files, a JSON object of all files plus metadata, and the frontend.
The frontend is a simple Javascript app. It uses Choo to render simple HTML views. The app is bundled with Browserify. To make writing CSS a little nicer, it is loaded with Sheetify and transformed through sheetify-nested.
