Usage

Overview

DarkIce as a live audio streamer. It records audio from an audio interface (e.g. sound card), encodes it and sends it to a streaming server.

DarkIce can record from:

* OSS audio devices
* ALSA audio devices
* Solaris audio interface
* Jack sources
* PulseAudio sources

DarkIce can encode in the following formats:

* mp3 - using the lame library
* mp2 - using the twolame library
* Ogg Vorbis
* Ogg Opus
* Ogg FLAC
* AAC - using the faac library
* AAC HEv2 - using the libaacplus (3GPP reference code)

DarkIce can send the encoded stream to the following streaming servers:

* ShoutCast
* IceCast 1.3.x and 2.x
* Darwin Streaming Server

Darkice runs on the following operating systems:

* FreeBSD
* Linux on intel and PowerPC
* MacOS X
* NetBSD / OpenBSD
* SUN Solaris

DarkIce uses POSIX real-time scheduling to keep up with sound card input. POSIX real-time scheduling is only available if the program is run as root. Therefore it is recommended that DarkIce is run as root.

Options

-c config.file

Specifies what configuration file to use. If not specified, /etc/darkice.cfg will be used.

-v n

Sets the verbosity level, between 0 and 10. 0 is silent, 10 is loud. Defaults to 1.

-h

Prints the help page and exits.

Notes

When using the FLAC encoder with an icecast streamer, make sure to increase the <queue-size> setting.
