encoding to fixed window length vorbis file
...ke file with window size = 256. Is there way to accomplish that? And now, why I need this. I'm working on ogg vorbis decoder optimised for SUN SPARC machines. SUN provides library (medialib, mlib) of multimedia functions, which are written in VIS assembly, so they are fast. I want to optimise bacward MDCT, and use medialib function for it. But here is a problem: medialib IMDCT has hard-coded buffer size = 256. It is not possible to use it for larger buffers (I think - I tried to use it twice on two halfes of 512 buffer on many ways). And the second problem is my project deadline is comming soon...
