About The Project

Technology

screenshot

The project is built using Electron/React/Express. The image above shows the simplified flow of audio data, from capture to playback on your Sonos device.

Capture

The project utilizes electrons desktopCapturer to capture raw audio. The stream of raw audio is captured in the format of 32 bit float.

Conversion

The server expects a stream of 16 bit signed integer. Hence the conversion before sending the stream to the server.

The stream is sent to the backend by IPC. Early versions of the software sent the stream via socket.io but the use of another package seemed redundant. I noticed no performance changes going from sockets to IPC.

Encode

The stream of 16 bit signed integers is encoded to mp3 with LAME. I had issues with the sample rate being inconsistent on different computers leading to a high/low pitched final result. To solve this I implemented an option to change the sample rate in the client.

Broadcast

The stream is now in the format of mp3 and ready for broadcast. The stream is linked to an endpoint served by express, the url of the endpoint is then sent by node-sonos to selected devices.
