slightly different audio output

Book/Literature
Hi, in order to understand the Ogg Vorbis decoding algorithm, do you recommend any document/book/www? I have read those on the web page but look for something more detailed..

size of vectors to be fed to MDCT
...As I have looked in the code, this "n" is chosen from the Ogg/Vorbis stream data in info.c:_vorbis_unpack_info() which means this "n" can vary aribitrarily (as the power of 2) depending only on the value got from song data? or is there any specific limit...

Greeting from Ogg on a Chip project
...ound that the computational intensive part starts from mapping0_inverse() and its children (mdct*(), res2_inverse(), and codebook.c) so I just thought this might be a part that we could implement it in hardware (if possible).

mdct.c
...unction in libvorbis and writing a small client program to test it. I found that I have to set ARRAYSIZE when mdct_init(lookup, ARRAYSIZE) to minimum value of 62 otherwise it will segfault with mdct_backward. Is there any lower limit or it is more likely that my code has bug? Thank you very much, Pattara -- Please avoid sending me Word or PowerPoint attachments.

mdct as hardware
Hi vorbis-dev! I'm working with Pattara in the oggonachip project, and wondering about the implementation of mdct.c as hardware. According your recomendations about using the floating point version, I would say, we have to implement the integerized version of mdct as a core, and use the fpu only to round the input values. By doing that,...

int or float?
...Integer running at higher speed. I'm not sure if 1) is possible (and if it is very difficult). And if it is possible, is it really beneficial (as it is mentioned that FPU is somehow faster esp. for multiplication than integer)? Thank you for all suggestion.

E.g. ./configure --something to set this (in the example) CC, AR, RANLIB variables and also special INCLUDEPATH or LIBPATH also in case that I compile the application (e.g. ogg123) not only the library.

Vorbis decoder chip: Specs needed
I'm considering creating an ogg vorbis decoder chip for my senior project in school. At this point, my idea is to have a program (such as XMMS, ogg123, WinAMP) send the encoded ogg bitstream through a USB port to my project, which is then decoded. My project then returns the raw PCM audio, which is then handled by the player program for final audio output. I'm planning on USB as it
