Processing-Enabled USB Audio Driver for Windows 10 and Windows 11

Features      Demo      Prices      

Thesycon’s TProcAudio solution is an extensible and highly customizable USB audio device driver for Windows. It supports USB audio class 2.0 and 1.0 compliant devices and can be equipped with custom signal processing (DSP) features such as down-mixing, up-mixing, EQ, effects, etc. In addition to (or instead of) the physical channels transferred over USB, the driver can expose virtual channels and sound devices to Windows to support use cases that involve multiple applications.


NOTE: The TProcAudio driver targets consumer or prosumer products. If you are looking for a professional audio driver with ASIO support, this is not the right approach for you. Check out our TUSBAudio driver instead.
