Well that's why I was hoping for a modified RLE, because the non repeated bytes are already stored decompressed in the source.
Will result in small symbol tables and quite large decompression routine :] The only issue will be the large symbol table (do not remember the correct name).Īnother idea: split SAP-R to 9 streams, delta them (good especially for AUDCn) and huffman, reverse when playing. If the entropy is low (and it is in SAP Type-R), this would yeld well over 9 times compression. I've just got this idea, what about using Huffman coding where alphabet is build from 72-bit letters (9 bytes).
Yes unfortunately for SAP-R, the window has to be 128-256 bytes for any decent compression,
