How would one implement the following scheme with minimal use of resources: Every Vorbis packet should be preprocessed to a certain extent, that is, the beginning of every audio packet should be parsed and some decoding steps executed. The result of this predecode as well as the rest of the packet should then be sent as output for final processing. I have skimmed through the standard, and as far

We've implemented a vorbis decoder based on Tremor and as part of the documentation we're also writing about psycho acoustic models and encoding. We're quite up to date with the decoding process and psycho acoustics in general but unfortunately not on the psycho acoustic encoding used in Vorbis. We have a few questions that would we would be very thankful to have answer to: Which

I wrote to the list earlier about optimizations of the tremor. Specially replacing the IMDCT with a N/4 FFT. The report is available here: http://www.sandvall.nu/thesis.pdf Short summary: Optimization of the Tremor code under 50kB for a "split" decoder version. ~44 MIPS. Huffman highly unoptimized. IMDCT ~ 8 MIPS. Quick overview of the
