HW-Speex: Fileformat and encoding process
...f the ogg file, which is not a sure
guess due to the -nframes option?
Is there a discription of the format of the frames. What is the reason that
the first frame after the header is larger than the other frames?
Thanks

Determining length of speex file speech
...and
then count in any ogg page the number of the ogg _frames_ (which, unless
I used -nframes while encoding, which I did not), and multiply this with
.02 (20 milliseconds).
I did this by hand, for example on the file I send yesterday when asking
about the noise, so the output of the program is:
$ readspx spfe49_1-small.spx
