butt

butt stands for broadcast using this tool and is a Linux tool that grabs audio data from your sound card (line-in, CD, wave, etc.), encodes the PCM data into MP3, and sends it to a streaming server (only Shoutcast is currently supported).

Streaming:

You can change the audio settings (bitrate, channels) while you are streaming.

Cause butt isn't a multithreaded application, the selection
of a new bitrate shouldn't take more than a few secs.

Otherwise the server may disconnect you, because it doesn't receive any data while you are looking for a new bitrate.

Recording:

Since version 0.1.1 butt is able to record and stream simultaneously - in diffrent bitrates.

For example you can stream with 96kbit and record with 192kbit.
