WHIP (RFC 9725) is a standardised media ingress protocol: it serves to stream audio and video to a network server, and is supported by a number of media distribution systems. PipeWire is the currently fashionable multimedia framework for Linux, and almost all Linux applications are able to send audio to PipeWire, either natively or through PipeWire's emulation of the ALSA and PulseAudio APIs.

Pw-whip is a bridge between PipeWire and WHIP: it enables every application that can speak to PipeWire to stream its audio to any compliant WHIP server.
