This is the fifth version (versions 1.00 and 1.10 supported only
RAW data, requiring a VOC conversion utility to be utilized). With VOC
support added, the program has been renamed from RAW2SAM to CVT2SAM to
demonstrate its multi-format input capabilities. Version 3.00 also adds
WAV conversion capabilities.
In each release you'll notice that I mention the code is 'very efficient' or
'optimally efficient.' At those points I was comparing my code to other
available code which performed the same tasks. When writing version 3.00
I discovered an entirely new set of routines which increase speed by epic
proportions! Following are a comparison between 2.20 and 3.00.
VOC files
(3,048,649 bytes in 13 VOC files which are a mix of raw VOC's, and many
different block arrangements)
Ver 2.20: 5 minutes 57 seconds
Ver 3.00: 1 minute 05 seconds
RAW and SAM files
(2,393,313 bytes in 11 files which are a mix of RAW, SAM, and SND files)
Ver 2.20: 3 minutes 42 seconds
Ver 3.00: 18 seconds
As you can tell, the speed increases were dramatic! Bear in mind, these
are my results on my system and do not guarantee any level of performance
(though I think you will find the performance outstanding!)
Version 3.01 (Mar 6, 1993)
Minor bug fixes of 3.00 (public release)
Version 3.00 (Mar 5, 1993)
Released only to select sites as 'test' release
SPEED! All routines were DRAMATICALLY speeded up. This program
should almost be a given a new name. Blazingly fast!!!!
Added ability to process WAV files
Fixed problems with incorrect lengths of silence block expansion
Version 2.20 (Feb 20, 1993)
VOC routines rewritten to be optimally efficient (were dependant
on RAW routines before for data processing)
Added '-R' option to reverse conversion from SAM to RAW
Added ability to expand VOC repeats
Version 2.01 (Feb 15, 1993)
Name changed to CVT2SAM to reflect new multi-format ability
Added VOC support (inlcuding blocked VOC's. Supported are:
message blocks, marker blocks, data blocks, subsequent
data blocks, silence blocks. Also recognized, but not
expanded were repeat blocks.
Added option '-C' to convert packed data
Added help screen '-?' online
Version 2.00 (Feb 15, 1993)
Very buggy version of 2.01, same features, but many didn't work.
A few copies leaked out before I caught the problems, which were
corrected within the day.
Version 1.10 (Dec 1, 1992)
Makes 1.00 more usable (no notable new features)
Added parameter reading routines so filenames can now be specified
on the command line
Complete rewrite of raw data to SAM conversion code (VERY efficient
now!)
Version 1.00 (Nov 92)
First release written for a friend
Converted raw data to SAM data
