AS3 Converter: RAW sound <-> ACC/Ogg/M4A/MP3

Input comes from standard Microphone object in Adobe AIR project (so 1 million billion bytes per second), needs to be effectively transferred to server and back to other users, and we have a slight preference for .ogg for that (but other conversion welcome, as long as the quality/file size ratio is acceptable and AIR knows how to interpret it). Q: You have a conversion procedure laying around somewhere? $200 if stand alone AS3 (so no external libraries required), bidirectional (wav->X->wav) and effective (<5K/s) If your "bid" doesn't start with "Hi Peter", you're blocked immediately, automated bids included!
