SOUND f1[,d1][;f1[,d2][;...]] [ON channels]

The SOUND command add a touch of interactivity and liveliness to your programs. Simply put, the SOUND command allows you to generate sounds directly from your computer. You can give just the frequency (to start an infinite sound) or a frequency followed by a duration. You can play multiple sounds by concatenating frequencies or frequencies and durations.

By combining several SOUND commands with different frequencies and durations, you can compose short melodies. For example, you can make a sound play when the user presses a button or reaches a goal in the game. You can simulate the sounds of explosions, gunshots, or any other effect you want.

This command allows you to handle multiple audio channels at the same time, if the target has them, allowing you to create more complex sounds. The waveform of the sound generated can vary depending on the available hardware.
