This sample program demonstrates how to use the Apple IIGS freeform sound 
playback capability.  It can be used to test digitized sound files which have 
been ported to the Apple IIGS .
_____________________________________________________________________________

The PlaySound window includes buttons for loading and playing digitized sound 
files.  The user can adjust the frequency and amplitude of the sample.  The 
files listed in response to clicking on the Load button are not limited to 
sound files, because existing third-party Apple IIGS sound applications use 
different file types for saving sound samples.  Sample.Sound can be used to 
experiment with PlaySound's features.

Additional Apple IIGS sound demos will be included in the next release of 
Sample Code.

Use APW 1.0 and Apple IIGS System Disk 3.2 or later to execute the PlaySound 
file included with the APW-compatible source code files.  To create a load 
file under APW, issue the following command:  ASML PlaySound.Aii 
Keep=PlaySound.

MPW IIGS users need MPW 2.02, MPW IIGS Tools 1.0, and any version of the MPW 
IIGS assembler.  The program name needed by the MPW Build menu's Build option 
is PlaySound.
