8SVX (8-bit Sampled Voice) is an audio file format that is part of the Interchange File Format (IFF) standard originally developed by Electronic Arts and Commodore for the Amiga computer. It stores mono 8-bit PCM audio samples and was the standard format for sound effects and instrument samples on Amiga systems. The format supports optional Fibonacci delta compression to reduce file size and can include loop points for sustaining sounds, making it widely used in Amiga games, trackers, and audio applications.
