Setting up the trig tables.
...=2048.
Assumption 3: M_PI is just PI, i.e. 3.1415....
Consider n=256, then n2=n>>1=128, n/4=64, n/8=32
first loop:
(i=0)
T[0]
T[1]
T[128]
T[129]
i=63 (last value)
T[126]
T[127]
T[254]
T[255]
econd loop:
i=0
T[256]
T[257]
i=31 (final value)
T[318]
T[319]

mdct.c pointer to array conversion
...r now) so I'm having to transfer the structure back and
forth using DMA. So the structure will have to be modified slightly so
the values from init->trig are contained as part of the structure. How
big should this trig array be?
Hope someone can make this less confusing,
Gov

Source file was keoki_passiton.ogg obtained from the Vorbis.com web site
some time ago (I don't think it is there any more). I'm using Version

the first audio block in the file (size 256).

Please correct this bugs in vorbis win32 environment
If You want to compile vorbis libraries under win32
environment you can experience some problems:
1) If you unzip vorbis libraries, you will have 3 directories:
"libogg-1.0", "libvorbis-1.0" and "vorbis-tools-1.0".
You need to rename them to "ogg", "vorbis", "vorbis-tools".
Otherwise batch files or even dsp project files, won't work.

Getting started with vorbisfile_example.c (MS VC 6)
Hello
Hope you don't mind another newbie's question.
Further to GIE's email about problems compiling decoder_example.c example
(MS VC 7) using debug static ogg/vorbis libs, we'd appreciate any help
getting the example files to compile on MS VC 6.
The zip files we have downloaded are:
libao-0.8.2.zip
libogg-1.0rc3.zip
libvorbis-1.0rc3.zip

mdct.h - PI1_8, PI2_8 etc.
In vorbis/lib/mdct.h the following are defined:
for integer:
#define TRIGBITS 14
#define cPI3_8 6270
#define cPI2_8 11585
#define cPI1_8 15137
#define FLOAT_CONV(x) ((int)((x)*(1<<TRIGBITS)+.5))
for floats:
#define cPI3_8 .38268343236508977175F
#define cPI2_8 .70710678118654752441F
#define cPI1_8 .92387953251128675613F
#define FLOAT_CONV(x) = x
Could someone explain where these values
