MelodyTrace

Every recording deserves a second life as notes

Play it once. Keep it as editable notes.

MelodyTrace listens to your recordings and writes down the melody as MIDI you can keep editing — then plays it back through real instrument voices as MP3. Everything happens right in your browser.

From sound to material

Notes out of any recording

A transcription model tuned for real-world audio pulls pitch and timing out of songs, riffs, hums and voice memos — MP3, WAV, FLAC and more.

Keep shaping the result

Detected notes land on a piano roll you can actually use: move them, stretch them, transpose a phrase, delete what you don't need, then export.

Give the MIDI a voice

Play your MIDI through a built-in grand piano or your own SF2/SF3 SoundFonts, and export a share-ready MP3 without any install.

Three steps, no setup

  1. 1

    Add a file

    Drop audio or video onto the workbench. Decoding starts immediately, and nothing leaves your device.

  2. 2

    Convert and refine

    Notes appear on the roll in seconds. Play them back, tune the detection, or fix details by hand.

  3. 3

    Export anywhere

    Download a .mid for your DAW, MusicXML for notation software, or an MP3 render for sharing.

Before you start

Yes — every converter on the site is free to use, with no watermark and no sign-up. The paid plan only adds convenience features like larger batch queues.

No. The transcription model is downloaded to your browser once and runs locally. Your audio, MIDI and SoundFonts never leave your device.

MP3, WAV, AIFF, M4A/AAC, OGG and FLAC, plus the audio track of MP4, MOV and WebM videos. On the output side you get MIDI, MusicXML and MP3.

Single instruments and vocals transcribe remarkably well. Dense mixes still yield usable material, though expect to tidy a few notes on the roll.

Yes. The whole site runs in a modern mobile browser — nothing to install and no plugins needed.
