Hi, it is kind of off-topic here, but as it is for the Flash Vorbis player and someone asked for it, here is at least a small part of the ActionScript for the Vorbis decoder. The problem is, as already mentioned, the performance. The Java code is running appr 40 times faster on my computer and the AS code must be improved a *lot* if a Flash Vorbis player should be performing reasonably: http://jarnbjo.de/Mdct.as http://jarnbjo.de/MdctFloat.java Thanks in advance for any useful feedback.
