- This archive contains a few simple but cute utilities for playing
- digital audio back through the D/A converter on the Delanco-Spry DSP
- board. The companion archives sounds1.arc and sounds2.arc contain sound
- fragments extracted from a large and growing number of MacIntosh sound
- novelties. They are good attention-getters at DSP demos (just ask
- W3IWI! :-) )
-
- The files are as follows:
-
- readme this file
- echo.hex Download image for TMS320 card
- echo.asm source for above
- play.exe Command for playing files
- play.c Source for above
- play8lin.asm Assembler assist for play.exe
- getopt.c Command option processing routine
- samprate.exe Sets sampling rate on DSP card
- samprate.c Source for above
-
- To play a file, first load the TMS-320 card:
-
- intel echo d000 300 1
-
- Then set the sampling rate:
- samprate 22000
-
- All of the files in sound1.arc and sound2arc were made at 22000
- kilosamples/sec except for horserac and hithere.
-
- play [-n times] filename1 filename2 ...
-
- This will play the files in order, optionally repeating each one by the
- number specified. The sound file format is simple 8-bit linear.
-
- If you recompile play.exe, make sure you specify the large data model.
