[vorbis] Location of fileinfo

hello there,

I just started using ogg files. And want to thank you all for this new
format.

I have written an addon for mirc (chatclient for irc chat networks) to
play and exchange soundfiles and I am almost done with implementing the
ogg vorbis format into this application.

The mirc-scriptinglanguage provides me a command to read a specified
number of bytes starting at a specified location of any file. It is this

command I have used to extract bitrate and frequency information from
wave-files.

I would like to do the same on ogg-files but I don´t know where to look
for that information in ogg-files.

My question: Could you please tell me how many bytes have been reserved
for nominal bitrate information and on what location this packet of
bytes starts? And the same for the frequency (khz) of the ogg-files.

Thanks a lot in advance,

Kind regards,

Danny Keff
