Hi all, I just have a few questions regarding the discrete cosine transform in dct64.c as I want to rewrite it on assembly level: - Which method was used to decompose the transform into smaller steps? Is this version regarded as the most efficient approach? - Has someone got a fancy signal flow graph of it? Or anything similar? - My assumption is that it synthesises from 32 subband frequency samples into the 32 time domain samples, right? So why is it called dct"64" then? Thanks!
