The audio is actually played by separate audio server processes which access the MME audio services on Alpha workstations. You may create audio player objects on other machines, and you may synchronize the starts and stops of audio segments with activities in your script, even if the audio is being played on a different machine. To play a different kind of audio, first close all audio players currently running on that machine and open a new audio player for the new kind of audio. The solution is to kill that program. You write commands to the audio player using write .
Commands take the form of lists.
The commands are outlined in the quick reference below. Be sure to also send the zero time to the audio player any time you reset your timer. You can control the volume of the audio device separably from the gain of the audio file you are playing. This will affect all audio streams playing on that machine. A gain of 1.0 means no file conversion will occur.
