<h1>The CELT ultra-low delay audio codec</h1>
<h2>Overview</h2>
<p>
- The CELT codec is an experimental codec for use in low-latency audio communication.
+ The CELT codec is a compression algorithm for audio. Like MP3, Vorbis, and
+ AAC it is suitable for transmitting music with high quality. Unlike these
+ formats CELT imposes very little delay on the signal, even less than is
+ typical for speech centric formats like Speex, GSM, or G.729.
</p>
+<p>
+ Using CELT application developers can build software that allows musicians to
+ perform together across the Internet, or simply build great sounding
+ telephony systems. Why shouldn't your telephone sound as good as your
+ stereo?
+</p>
+<p>
+ Like other open and unencumbered technology from the Xiph.Org Foundation CELT
+ requires no royalties and no complicated licensing.

<p>
The CELT codec is meant to bridge the gap between Vorbis and Speex for applications
where both high quality audio and low delay are desired.
