What is a .SF3 file?
SF3 is a SoundFont with its samples compressed as Ogg Vorbis.
- Did you know
- SF3 shrinks a SoundFont by compressing its instrument samples.
- SF3 was devised by MuseScore as a near-identical variant of SF2 whose samples are squeezed with Ogg Vorbis.
- The Ogg compression can leave an SF3 roughly ten times smaller than the equivalent uncompressed SF2 bank.
- What Analyser reads
- Identify many more audio formats: lossless/hi-res codecs (Monkey’s Audio, WavPack, TAK, True Audio, DSD/SACD, Musepack), pro containers (Core Audio, RF64/BW64, Wave64, Sun AU, Broadcast Wave with timecode), speech/mobile (Speex, AMR-WB, QCP, 3GA, M4R, GSM), MPEG Layer I/II, instrument banks (SoundFont, SFZ, DLS, RIFF MIDI, GigaStudio), ringtones (RTTTL, iMelody, SAP), tracker modules (MOD, XM, IT, S3M, OctaMED, 669, Oktalyzer), chiptunes (NES NSF, SNES SPC, VGM, Game Boy GBS, AY, YM) and Audacity projects.
- Depth of analysis
- .SF3 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .SF3 file
- Drag a .SF3 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
