What is an SFX file?
An SFX file is an audio file saved in the SoundFX format. It is similar to a SoundTracker (.TFMX) file, but is designed for sound effects. SFX files may include patterns and audio effects, but are typically short in length.
The programs that created SFX files are no longer developed or maintained. However, they may be recognized by some audio tracker programs like OpenMPT.
