PCPLAY version 1.2 May 29, 1993 by John A. Ball
PCPLAY is a utility for playing back sound files on any regular
PC. It does not require a sound board. To use the program type
PCPLAY filename
Version 1.2 will play back Tandy Sound files (SND), Creative Labs
(VOC) files, Microsoft (WAV) files and Amiga (IFF) files. It will
try to play back unknown files at 11,000 samples per second. The
sound files should be uncompressed, 8 bits, and unsigned.
PCPLAY does support the use of a DAC such as in the Sound Blaster
Board or the newer Tandy Computers. There are also other commands
and options which may be viewed by typing PCPLAY/? .
The main program is written in C and the sound routine for the PC
speaker is written in assembler. I used QuickC 2.51 with Assembler
to create this program.
There are limitations to this program.
1) It does not play back VOC files that have multiple voice segments
or use the silence blocks.
2) It does not play back both channels of stereo files on some output
devices, i.e. Sound Blaster.
3) The pitch or playback frequency is not always correct.
4) PCPLAY does not play back sound files which have been compressed.
Undocumented Commands
1) /x debug mode gives program information about what is happening
2) /# use linear conversion table for PC speaker
The use of this program is free. The source code for this program
is available for purchase. Comments and suggestions may
be sent to
