What is a .RMI file?
RMI wraps a MIDI song in a RIFF container, sometimes with embedded instruments.
- Did you know
- RMI lets a MIDI file carry its own sound bank so it plays the same everywhere.
- RMI is Microsoft’s wrapper that places a MIDI sequence inside a RIFF container, identified by the RMID chunk tag.
- The MIDI Manufacturers Association later extended it so a file could embed a DLS instrument bank, letting the tune carry its own sounds.
- 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
- .RMI 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 .RMI file
- Drag a .RMI 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.
