# SFOTool for TinySoundFont A tool to create heavily compressed .SFO files from .SF2 SoundFont files. ## Purpose SFO files are just regular SoundFont v2 files with the entire block of raw PCM samples replaced with a single Ogg Vorbis compressed stream. Unlike .sf3 files, which can have every separate font sample compressed individually, this will compress the entire sound data as if it were a single sample. This results in much higher compression than processing samples individually but also higher loss of quality. ## Usage Help ```sh sfotool <SF2/SFO>: Show type of sample stream contained (PCM or OGG) sfotool <SF2> <WAV>: Dump PCM sample stream to .WAV file sfotool <SFO> <OGG>: Dump OGG sample stream to .OGG file sfotool <SF2/SFO> <WAV> <SF2>: Write new .SF2 soundfont file using PCM sample stream from .WAV file sfotool <SF2/SFO> <OGG> <SFO>: Write new .SFO soundfont file using OGG sample stream from .OGG file ``` ## Making a .SFO file from a .SF2 file 1. Dump the PCM data of a .SF2 file to a .WAV file `sfotool <SF2> <WAV>` 2. Compress the .WAV file to .OGG (i.e. with [Audacity](https://www.audacityteam.org/download/legacy-windows/)) Make sure to choose the desired compression quality level 3. Build the .SFO file from the .SF2 file and the new .OGG `sfotool <SF2> <OGG> <SFO>` # License SFOTool is available under the [Unlicense](http://unlicense.org/) (public domain).
