Why WAV produces better MIDI results

WAV is a lossless, uncompressed audio format. Unlike MP3 which discards audio data it considers inaudible, a WAV file contains the full waveform. This gives the pitch detection algorithm a cleaner, more accurate signal — especially for notes with fast attacks or for separating closely pitched instruments.

If you have the choice between an MP3 and a WAV of the same recording, the WAV will generally transcribe to MIDI with better note accuracy and fewer artifacts.

Three conversion modes

Full Mix (Mode A) — converts the whole audio to a single MIDI track. Best for monophonic recordings like a solo guitar, bass, or vocals.
2 Tracks (Mode B) — uses harmonic-percussive separation to split pitched notes from drum hits. Outputs separate melody and drum MIDI tracks.
4 Tracks (Mode C) — separates drums, bass, melody, and other into four individual MIDI tracks using spectral analysis.

How to convert WAV to MIDI

Drop your WAV file onto the tool above, or click "Choose WAV file" to browse.
You'll be taken to Filesmith's audio workspace automatically.
Click the 🎹 → MIDI button to open the MIDI panel.
Choose your mode (Full Mix, 2 Tracks, or 4 Tracks) and click Convert to MIDI.
Download your .mid file when it's ready.

Open the MIDI in your DAW

The output is a standard .mid file compatible with all major DAWs — FL Studio, Ableton Live, Logic Pro, GarageBand, Reaper, Pro Tools, and more. Import it to get editable MIDI notes, then layer instruments, adjust timing, or use it as a starting point for a new production.

What to feed it

Transcription accuracy depends far more on the recording than on any setting. What helps, in rough order of impact:

One instrument at a time. A solo line transcribes well; a full mix is the hardest case there is.
No reverb. A long tail blurs where one note ends and the next begins, which is exactly the boundary the algorithm is trying to find. Record dry and add reverb later.
Clean, sustained notes. Slides, bends and heavy vibrato move continuously through pitch, so they resolve into a smear of short notes rather than one.
Trimmed silence. Room tone and handling noise at the start can register as spurious low notes.

Sample rate matters less than people assume. 44.1 kHz is ample — pitch detection works on frequencies far below the ceiling that a higher rate buys you.

Tidying the result in your DAW

Treat the output as a first draft. Three fixes cover almost everything:

Octave errors. The most common failure in pitch detection — a note lands an octave above or below where it belongs, because the algorithm locked onto a harmonic instead of the fundamental. Obvious in a piano roll, quick to drag back.
Stray short notes. Filter out anything under about 50 ms and most detection noise disappears in one pass.
Timing. Quantise lightly rather than fully — hard quantising a transcription usually removes the feel that made the performance worth transcribing.

Frequently asked

Will the MIDI capture every note?

It depends on the source. Solo instrument recordings convert with high accuracy. Full mixes, distorted audio, and recordings with heavy reverb are much harder to transcribe accurately.

Why use WAV instead of MP3 for transcription?

WAV is uncompressed and lossless, which gives the transcription algorithm cleaner data to work with than a lossy MP3. The accuracy improvement is usually small but real, especially for soft or quiet recordings.

What can I do with the MIDI file afterward?

Import it into any DAW (FL Studio, Ableton, Logic, GarageBand, Reaper) to edit notes, change instruments, transpose, or build new productions from the transcribed melody.
