Hi,
I am currently porting the Vorbis Decode on Arm9 Processor. I am debugging
the IMDCT code. But I am unable to understand the algorithm.
Is it FFT implementation? if not is there any document about the algorithm
implemneted in tremor. I also gone through this document
" The use of mul-tirate filter banks for coding of high quality digital
audio [http://www.iocon.com/resource/docs/ps/eusipco_corrected.ps]"
by T. Sporer, K. Brandenburg and B. Edler.
But it is to mathematical. I am unable to understand the signal flow diagram
implemneted.
