Hi everyone, I'd just like to announce version 0.4.0 of CELT. CELT is a new very low-delay audio codec designed to have <10 ms delay at 44.1/48 kHz. This new release should improve the handling of transients and reduce the amount of pre-echo on things like castanets, especially for larger frame sizes. There is now support for frame sizes up to 512 samples for those who don't have extreme delay requirements. There's been some more tuning for stereo and a variety of frame sizes and higher bit-rates. The API has been changed slightly to remove the overlap parameter, which is now automatically selected based on the frame size. Download it from the website: http://www.celt-codec.org/ Cheers, Jean-Marc
