slightly different audio output

In theory, must they deliver exactly the same audio output or some
errors are tolerable.
Thank you very much,

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..
Thank you very much,
Pattara

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...
Thank you very much,

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). Do you have any comment? Are we on
the right track?
Thank you very much,
Pattara

...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,

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.
Greeting from the south of Germany,
Pattara

Anybody has an idea here? Or something with my device driver (I have

...to* stuff and I
wonder if there is any easier and more intelligent way to do this. 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.
Thanks much,

Pattara Kiatisevi [15]announced the Ogg on a Chip project, which will
implement Ogg in form of a "system-on-a-chip" using "hardware/software
co-design techniques". More information on the project can be found at

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
