We've been using the Secret Rabbit for some time now, and are very pleased with it. The only thing that really has kept us from enthusiastically adopting Libsndfile as well has been lack of Broadcast Wave File (BWF) support. You can find BWF documented in EBU Pub 3285, at: http://www.ebu.ch/CMSimages/en/tec_doc_t3285_tcm6-10544.pdf A couple of the Supplements are important for our purposes too: Supplement One - MPEG Audio http://www.ebu.ch/CMSimages/en/tec_doc_t3285_s1_tcm6-10545.pdf Supplement Three - Peak Envelope Chunk http://www.ebu.ch/CMSimages/en/tec_doc_t3285_s3_tcm6-10483.pdf We do not need to transparently encode or decode MPEG data to PCM (we use a hardware codec for that), but we do need to be able to read/write raw MPEG frames into the DATA chunk as defined in Supplement One. Given your long-standing policy of non-support for MPEG, I was not sure if this was something you would be interested in adding to libsndfile.
