About

Built for audio that has to work in the real world.

Impetus DSP is an independent audio software brand focused on useful, low-friction signal processing. The goal is simple: make difficult audio easier to listen to without sending user audio to a server.

Future work may include VST and CLAP plug-ins that bring the same practical approach to desktop production workflows.
