Hi,

   I will porting tremor to 24bit DSP. DSP compiler don't support malloc 
ANSI C function. i want to use the static array to replace these dynamic 
memory. But size of the allocate buffer is depend on the parameters from 
vorbis bitstream.Vorbis spec.don't give the limit of these parameters,and 
theroy values deduced from bit width is very large.for 
example,codebook_dimensions and codebook_entries.
   Because DSP has 60Kbyte data memory(RAM+ROM),low memory tremor exceed 
60Kbyte. I want to remove floor0 and other window size than 256 and 2048 to 
save memory. Does vorbis I encoder support floor0 and other window size? 
Are there any ogg vorbis files of use floor0? 
   how to log in tremor svn?

Thx
Sam
