...e zeros). Hope that clarifies things (and doesn't break too much
> stuff).
so is the following correct, for the example you gave (narrowband):
1) decoding the first packet produces 80 samples, and it has a granulepos
of 80.
2) decoding any subsequent packet produces 160 samples, and has a
granuelpos "N*160 - 80"
?

Ogg FLAC
...any other byte
stream into the Ogg with the same method, e.g. you could put an Ogg into
another Ogg.
A better aproach would be to, not to embed the whole FLAC file into the Ogg
itself, but the single audio frames the way done with Vorbis frames (Ok,
they are called packets there). If so, the best granuelpos would be the
sample position, like in Vorbis.

Speex granulepos definition
Jean-Marc,
What exactly does the speex code do to calculate the granulepos? With
vorbis it's the 'count of decodable samples including this packet'. So
if you had a packet that allowed you to decode 1024 samples since the
beginning of playback, the granulepos is 1024, not for example 1023
which would be the *index* of the last sample assuming C-style array
indicies starting at

OK, gotcha. but currently flac does put one FLAC frame per
packet. the exception, and a bug looking at the code again,
is that it also uses the first packet for the FLAC metadata
but is using 0 for the packet number of both the metadata an...

Feedback on Ogg Speex file format
Hi,
I'm the main author of Speex (http://speex.sourceforge.net), an
open-source speech codec that uses Ogg for file storage. I'd like to
have feedback on the way we store Speex data in Ogg files to make sure
we do the right thing. The Speex documentation can be found at
http://speex.sourceforge.net/manual/ but here's the part about Ogg:
