SFX is for short reusable samples, usually game and user-interface sounds. The usual pattern is to load a sample once with Sfx Load, then play it whenever the program needs that sound.

The id is a number chosen by the program. After loading id 1 with a click sound, Sfx Play 1 plays that click. The channel forms let a program decide where the sound is mixed, and the optional pitch value changes playback speed for simple variation.

Sfx Loop repeats a sample until it is stopped. That is useful for engine hum, wind, alarms, or any sound that should continue while something is happening. Stop, Pause, and Resume can affect all effects, one loaded id, or one channel depending on the form used.

Sfx Status lets a program ask whether any effect is active, whether a specific id is active, or whether a specific channel is active.
