Sierra's SND format was created for the AGI engine that powered most of Sierra's early games including the very first AGI game, King's Quest (PCB). It was developed to store music for the PCjr's 3 voice chip. Data is stored in four streams, the first channel is the melody, the second and third channels are harmony, and the fourth channel is the noise channel. On computers with a PCjr 3 Voice or a Tandy 3 Voice chip, all four channels would be played, but on computers with only a PC Speaker, just the first channel would be played.

Sierra did not use the *.SND extension. Inside of its file archives (called volumes), the sound files are stored simply as SOUND.000, SOUND.001, SOUND.002, etc. The SND extension is used because the AGI Sound Edit program uses the extension to identify the files.

Currently, there are no players that can properly emulate the 3 voice aspect of the format or play the noise channel.
