CELT LCA

Position:

This talk introduces CELT, a new open source codec from Xiph.Org designed for high-quality communication with very low delay.

• We want very high quality VoIP/videoconference/...
• Speex doesn't reach a high enough quality level and Vorbis has too much latency.
• For once, open-source is ahead of the proprietary codecs.

Possible contents:

• Explaining why latency is an issue
• How CELT works
• API and writing for low latency
• Comparison, samples
• Low-delay demo (e.g. vs Skype or Ekiga)
