SPC700 sound format
An SPC700 sound file (or SPC) is a type of video game music file consisting of a copy of the 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, mostly ZSNES, rather than from the system itself). Because the SPC700 is a finite state machine, it is possible to cause the chip (or emulator thereof) to reproduce the sounds which were "in the queue," so to speak, simply by restoring this data to its original place in memory. Since most SNES games loaded entire songs into SPC memory at once (using a format comparable to MOD or IT), it is possible to store music which might otherwise take up several megabytes in only 64 kilobytes of data. SPC files can be played through Winamp using a plugin called SNESAmp, Alpha II SPC Player, Foobar2000, or through DeliPlayer. They can be played at samples above native sample rate (32 kilohertz). SPC700 sound format is akin to PSF format from the Sony Playstation.See also: NSF, VGM, GYM, PSF and PSF2
