An SPC700 sound file (or SPC) is a type of video game music file consisting of a copy of a program and music data from RAM used by the SPC700 sound chip on the Super Nintendo Entertainment System or Super Famicom (though such data is usually obtained from a console emulator such as ZSNES or Snes9x, rather than from the system itself). The SPC700 chip (or emulator thereof) produces sound by executing the embedded program, which processes the stored music data and transforms them to a set of DSP commands responsible for reproducing sounds. The capabilities of the SPC700 DSP commands allow for music synthesis by samples (analogous to MOD or IT music playback); therefore it is possible to store, in only 64 kilobytes worth of data, music which, if stored as a digital audio waveform (e.g., the format used in CDs), might take up several megabytes.
SPC plugins are available for Winamp (see SNESAmp), foobar2000, and other popular players; a few have native SPC support. Some SPC players can even produce higher-quality output than the SPC700 itself. And there is also a program by the name of SPC2MIDI able to produce MIDI files from SPC files.
