What is a .FST file?
FST is an Amiga music module of the Future Composer family - a repacked player format of the kind that circulated in games and demos rather than a tracker document in its own right.
- Did you know
- Repacked music formats like FST exist because Amiga developers routinely stripped and re-wrapped player data to squeeze it into a game's memory budget. (approximate)
- Analyser handles .FST alongside related formats such as .MOD, .XM, .IT and more.
- In Analyser's format library, .FST sits in the System & disk category.
- What Analyser shows you
- Play and analyse tracker modules - MOD, XM, IT, S3M and around sixty relatives from the demoscene and the Amiga and DOS eras. A module is not recorded audio: it is a bank of instrument samples plus a pattern score saying which sample to trigger, on which channel, at which row, so playing one means running a tracker engine. Analyser renders the song on your device with libopenmpt - the engine behind OpenMPT - and then treats the result like any other audio, so you get the full Sound section: waveform, spectrogram, transport, loudness, key and BPM. Above it sits the module itself - the tracker that wrote it, the channel, pattern and order counts, the song message, and the sample and instrument name lists, which is traditionally where authors left their greetings. The rendered song can be saved as a WAV.
