Vorbis dev - Aug 2009 - Urgent Doubt in VORBIS

Is the decoded pcm size of an encoded stream equal to the raw input sample's
pcm size? or Are they different?

      raw sample(pcm sz1) --> encode --> decode(pcm_sz2)

      Is (pcm_sz1 == pcm_sz2) ?

Could Anyone please clarify....

Thanks
Sumit

The number of samples will be the same. The size depends on what
format your input and output are - libvorbis natively uses floats, for
both input and output, so they'll be the same - but if you convert to
an integer format, of course, they won't be.
