Hi, as we are trying to implement MDCT in hardware, we are caring now about the "n" (size of input and output vectors to and from MDCT).

However i am facing the following problem (which I think is more of C than vorbis) 1. after single steppig I finally arrive at the function shown below (in file lib/info.c) static int _vorbis_unpack_info(vorbis_info *vi,oggpack_buffer *opb){ 196 codec_setup_info *ci=vi->codec_setup; 197 if(!ci)return(OV_EFAULT); 198 199 vi->version=oggpack_read(opb,32); 200 if(vi->version!=0)return(OV_EVERSION); 201 202 vi->channels=oggpack_read(opb,8); 203 vi->rate=oggpack_read(opb,3...

I'm trying to fully determine the file format for Ogg Vorbis audio files as produced by oggenc and I'm having a hell of a time. :) I've sorted through all the online documentation I can find. I've downloaded the latest CVS source respositories, sifted through the documentation there, and tried sifting through the source as well. I should state that I'm not a C guru (I
