The Sierra On-Line Interpreter audio format was created by Sierra On-Line for their games that used their SCI engine. The format is very similar to MIDI, however, it houses specific instructions allowing it to be played on various devices. Depending on the device, instrument PATCH files must be sent as system exclusive data.

SCI files have 16 tracks, but no more than 4 are ever used for a particular device. Also, multiple devices can use the same tracks. For example, the PC Speaker usually uses track 0, and 3 Voice Chipset devices use tracks 0, 10, and 11. Devices using the LA32 and the Yamaha Chipset often used the same rhythm tracks, but had different percussion tracks. The SCI format has the ability to support the LA32, Yamaha Chipset, Casio Chipset, OPL2, General MIDI, 3 Voice Chipset, PC Speaker, and PCM audio, though not every game supports each protocol.

The SCI file extension was never used by Sierra. Instead, they gave their audio files numbered extensions like *.000, *.001, *.002, and so on.
