ugBASIC User Manual

   BOOM [duration [MS]] [ON channel]

This command makes the computer emit an explosion-like sound. It is possible to indicate the duration of sound effect and on which voices the system should emit the sound. If omitted, it will be issued on all.

Note that the execution of the effect can be synchronous or asynchronous, depending on the target. Synchronous execution means that the program will wait for the effect to complete before returning; on the contrary, asynchronous execution requires the program to continue executing subsequent instructions.

The behavior can be modified by the DEFINE AUDIO SYNC and DEFINE AUDIO ASYNC pragmas, which however may not be available for the target in question.
