Short: Fibonacci (de)compression for 8SVX
Author: wnoeker@t-online.de (Wilhelm Noeker)
Uploader: wnoeker@t-online.de (Wilhelm Noeker)
Type: mus/misc
"wavepak" is a Fibonacci-Delta / Exponential-Delta encoder/decoder for
IFF 8SVX samples. Both are efficient, but lossy, compression techniques:
They are fast and achieve a guaranteed compression ratio of 50 %, but at
the cost of some 'quantization' noise.
Exponential Delta differs from the well-known Fibonacci Delta compression
only by the compression table that it uses. I believe it results in less
distortion than FDC. It is not an official standard (yet?), comments are
welcome.
"wavepak" is Freeware, C source is included.
