opus - Nov 2010 - Frame_size?

"frame_size = PCM audio in signed 16-bit format (native endian). There must
be exactly frame_size samples per channel."

 

Sorry for such a simple request, but could you please clarify the definition
of frame_size when using stereo audio channels? When you say "frame_size
samples" does this mean that, if my frame_size is defined as 128, there are
64 left samples and 64 right samples per frame? Or does this mean 128 left
samples + 128 right samples per frame? I believe you mean the latter, but
just wanted to make sure.

 

Thx

MikeH

The latter. 128 means 128 left plus 128 right. 128 samples per
channel.  The I/O to CELT is all interleaved (as is typical for
audio).
