The SoundTest utility for RISC-OS

SoundTest is a test of the VOICES and SOUND capabilities - such as are required for the application !SignalBox to run. During the development phase of the Iyonix where sound worked but suffered many problems, this utility showed up the difficulties until they were fixed. It now controls its appetite for the sound buffer to prevent it overfilling it! It could be used for the same testing purpose on the A9home. On its own it is of no other use!
