What is a .PSF2 file?
PSF2 is the PlayStation 2 variant of the Portable Sound Format - it embeds a game’s actual sound program and data so a player can emulate the console’s audio.
- Did you know
- A PSF2 plays music by running the original game code in a tiny emulator, so the tune sounds exactly as the console produced it.
- PSF2 extended the original PlayStation PSF to the PS2, the same idea that produced GSF, SSF and USF for the Game Boy Advance, Saturn and Nintendo 64.
- Inside, a PSF2 uses a small virtual filesystem to hold the game's sound program and samples, compressed with zlib.
- 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. DJI waveform peak sidecars (PKF - the overview a DJI recorder writes beside its audio) are drawn as a waveform; Adobe Audition peak caches (also PKF) are identified.
- Depth of analysis
- .PSF2 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 .PSF2 file
- Drag a .PSF2 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.
