About

BUTT (Broadcast Using This Tool) is an easy to use, multi OS streaming tool.
It supports Icecast, Shoutcast and WebRTC and runs on Windows, macOS and Linux.
The main purpose of BUTT is to stream live audio from your computers microphone or line input
to an Icecast, Shoutcast or WebRTC (WHIP) server. If you want you can also record your broadcast locally
on your computer.
With BUTT you can not directly stream audio files. However, with the help of tools like
Voicemeeter (Windows), Blackhole (macOS) and PulseAudio (Linux) you can also stream audio files
directly from your favorite music player.

For more details and instructions have a look at the Manual [PDF]
