I have been playing with the usc_speech_codec sample to compress a wav file that is
800K in size, and I would assume that compressing it with G729 should give me a
size reduction factor of 16:1 (160bytes -> 10 bytes), hence I would expect an output
file of 50K in size, but I'm actually getting a file of 81K in size.
Am I missing something obvious?

Hi,
USC output file designed to allow USC decoder to automatically detect used speech codec and corresponding bitrate. To realize itframe header in the length of 6 bytes stored before every compressed frame.Adding of theframe header occuresonly on application level and all USC codecs returns clear bitstream.
