Primarily a central place to keep all my work relating to acoustics - software, hardware, modelling and system design. It can also be described as an audio streaming platform which receives data from multiple audio sensors, stores the data and forwards it to a pretty Svelte UI which shows time and frequency domain data

GoTCPWebSocketAdapter --->SvelteKitUI
- AudioSensor - RasperryPi with Respeaker array which transmits multiple channels of audio data
- AudioSimulator - Windows simullator which can generate multiple channels with a specific tone and phase offset
- ProcessingServer - Server which hanfles multiple TCP connections from sensors, write their audio data as WAV and forwards it to the websocket converter
- GoTCPWebSocketAdapter - Forwards data from server to web front end
- SvelteKitUI - UI that displays sensor data
Contact me (Grant Norrie) on linkedin. I shall provide an RPi 3B + image. Flash this turn on the PI and it will automatically start recording all audio and provide a UI to see what is going on. Below is are examples of the UI:
View multiple live or simulated data streams from multiple devices. System information is also propogated to the UI.
Multiple Sensor positions (set statically or using a live GPS position) may be sent to and displayed on a map.
Audio files will be generated and written to a user specified location. In this case an external drive.
