What is a .MPP file?
MPP is a Musepack audio file, an older extension for the same lossy music codec as .mpc and .mp+. In the wild the same extension far more often means a Microsoft Project plan.
- Did you know
- Musepack used .mp+ and .mpp through its MPEGplus years and .mpc after the rename around 2000 - successive eras of the codec rather than interchangeable names, since the stream versions behind them differ.
- The .mpp extension dates from Musepack's MPEGplus era, before the project settled on the .mpc name.
- Sharing the extension with Microsoft Project files is pure coincidence - the audio codec and the project planner are unrelated.
- 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
- .MPP 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 .MPP file
- Drag a .MPP 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.
