Extract text from MIDI audio files (RMI)
To convert RMI MIDI files to another format, you need Microsoft Windows or other Audio software.
To convert other file formats to the "RIFF MIDI or Video Index" file type, you need software like Microsoft Windows or a similar tool.
The .RMI file extension is most commonly used for two distinct purposes: as a DVR Video Index file generated by Raysharp DVR systems (36% of cases), or as a RIFF-based MIDI Audio file native to legacy Microsoft Windows environments. When used in security systems, the file stores timestamp and navigation metadata for CCTV recordings. When used as an audio file, it acts as a Resource Interchange File Format (RIFF) wrapper around standard MIDI instruction data, sometimes bundling custom Downloadable Sounds (DLS).
Legacy .RMI audio files can be opened with classic software like Windows Media Player, VLC Media Player, or Winamp. In contrast, DVR index files require the proprietary Raysharp DVR viewer software and are useless without the accompanying raw security video files.
You will frequently encounter playback problems with .RMI files. As an audio format, it is ancient and completely unsupported by modern web browsers, smartphones, or standard streaming platforms. Its playback also depends heavily on the host device's MIDI synthesizer, meaning it will sound completely different depending on where you play it. As a DVR index, it is a locked-down proprietary metadata file that prevents you from simply playing the security footage in standard video editing software.
To fix audio playback issues, you must convert .RMI audio to modern formats. Convert to MP3 for web streaming and mobile listening, or WAV for high-quality audio editing without compression loss. If the file is a standard MIDI wrapper, you can also strip the RIFF header to extract the raw MID file. Drop your file here to analyze and convert it securely right in your browser - free, online, and without installing software via convert.guru. Note: DVR index files contain no actual video data and cannot be converted to video formats independently.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RMI converter.
