Input
Existing .mid/.midi files with text meta events that need encoding cleanup
MIDI formats
Output
Browser-local MIDI output in the selected encoding; notes, timing, tempo, velocity, and controllers are kept unchanged
Use case
Garbled MIDI lyrics, track names, instrument names, markers, cue points, and copyright text cleanup
Choose by input and output needs, then comparable tests, published evaluations and capabilities. Missing scores do not imply lower quality; more parameters or a newer release do not prove superiority. This is a suggested usage order, not an overall leaderboard.
Cost, time, formats and parameters depend on the selected model.
AvailableMIDI Converter follows mason369/midi-encoding-converter: it rewrites existing MIDI text meta-event encodings to the selected target encoding in the browser, with UTF-8 as the recommended default, without upload or model inference.
The MIDI converter is the mason369/midi-encoding-converter path for browser-local MIDI text meta-event recoding.
Parses LRC and Standard MIDI File bytes directly and writes FF 05 lyric events without a neural model.
Official repository - current
The converter repository documents the binary MIDI parsing path: parse MThd/MTrk chunks, find text meta events 0x01-0x07, decode source text bytes, re-encode to the target text encoding, recalculate track lengths, and write MIDI output. No neural paper or model ranking applies.
MIDI Manufacturers Association - current
The MIDI Manufacturers Association specification defining how lyric meta events are stored inside a Standard MIDI File, which is the exact structure this tool writes when embedding timestamped LRC lyrics.
No public paper link is listed; use the official repo or runtime implementation as the source.

Supported formats: mid, midi - Max 10 MB
Used when auto-detect is off. Applies only to MIDI text meta events, not notes or timing.
Browser-local mode writes the selected target encoding: UTF-8, Shift_JIS, GBK, Big5, EUC-KR, or ISO-8859-1. UTF-8 remains the recommended default for modern DAWs and MIDI editors.
