This app is a simple HTTP-based API for controlling output and input volume levels and mute status on a Windows PC. It will allow you to list out all your sound cards, plus inputs and outputs. You can control mute, unmute, and volume levels with simple HTTP requests.
If you’ve ever needed to remotely control microphone or speaker volumes on a Windows PC, this web API lets you do that.
I created this application to allow us to quickly remotely control audio on drone PCs sent to clients for virtual and hybrid productions.
Huge thanks to the NAudio project - this app uses the NAudio library for control.
