Crec as is it is pretty useless with PCM only...If we added the profile 
selection and things like bitrate information it'd be straightforward to 
support elementary bitstreams like MP3 or AAC ADTS, you just dump the 
data to a file. Things that require a header or MP4 integration would 
require additional libraries, this is no longer 'tiny'.
