Short: High Compression ratio for SAMPLES/MODS Author: of amiga port Gianluca Marcoccia (marcocci@cli.di.unipi.it) Uploader: Gianluca Marcoccia (marcocci@cli.di.unipi.it) Type: util/pack Shorten v1.22 A High Compression ratio utility for SAMPLES/MODULES Copyright 1992-1995 Tony Robinson This program uses a special prediction algorithm to predeterminate how the waveform will evolve and then a specially tailored huffman algorithm to compress the residuals. The compression so achieved can reach 2:1 ratio, which is far better than that of general purpose compessors as PKZIP, LHA, etc... I started rewriting some pieces of code in optimized ASM code, but I decided I would release this version (which is working quite nicely already) in order to see how many people were interested in this piece of software. IF I WILL GET ENOUGH DEMAND, I might provide a MUCH faster version of this, and even a xpk library containing optimized code. This port of this piece of software is E-Mail-Ware, this is a new conception of freeware: if you use it, and if you have access to a place where you can send E-Mail, send me a mail, telling me what you like and dis-like about this. (even just 'I am using it' will suffice) Versions for 68000/020/040/881 supplied. *math coprocessor highly suggested* ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 3405 1784 47.6% 17-Apr-95 21:06:04 +AMIGA.README 6274 2858 54.4% 10-Jan-95 07:18:00 +change.log 936 538 42.5% 10-Jan-95 07:07:18 +LICENSE 10190 4286 57.9% 06-Jan-95 09:12:24 +shorten.1 11864 4730 60.1% 10-Jan-95 07:06:36 +shorten.man 146942 54662 62.8% 03-Jan-95 18:41:04 +tr156.ps 33801 12940 61.7% 03-Jan-95 18:40:24 +tr156.tex 47044 20732 55.9% 17-Apr-95 17:54:32 +shorten000 44280 20042 54.7% 17-Apr-95 17:50:24 +shorten020 32268 15118 53.1% 17-Apr-95 18:04:00 +shorten881 -------- ------- ----- --------- -------- 337004 137690 59.1% 18-Apr-95 18:00:20 10 files
