What Tremo is
Tremo is a web service for converting audio into sheet music and MIDI, plus separating vocals and instruments. Its sheet-music converter accepts an MP3 or WAV upload or one YouTube link, with multiple sources unsupported. Simple Melody extracts a single-line melody from vocals or lead instruments. Piano Melody provides Harmony, Rhythm, and Note Duration controls, each set to 0, 1, or 2. Users can preview PDF scores, play MusicXML results, and inspect MIDI in a piano roll with play, loop, and zoom controls. Audio Separation accepts MP3, WAV, or FLAC files or one YouTube link, offering Vocals + Instrumental and Full Stem Split modes. Tokens are charged when conversion starts, while plan duration limits still apply. Plans range from Free at no cost with 20T and three-minute tracks to Light at $9 a month and Pro at $14 a month. Studio uses a custom quote.
