WAV source profile
Lossless detail helps when the recording is already clear.
- What WAV preserves
- Uncompressed or lossless samples retain attacks and dynamics without adding codec artifacts.
- What still causes errors
- Room noise, clipping, reverb, and competing instruments can matter more than the file container.
- Best use here
- Use dry stems, clean instrument takes, and DAW bounces with the target part near the front of the mix.
How it works
Start with your cleanest WAV take
A dry, isolated melody or instrument recording generally gives the transcription model a clearer signal than a dense full mix.
- 01Upload the lossless takeChoose a WAV file up to 50MB and five minutes, with the target part clearly audible.
- 02Preserve the useful detailThe service sends the recording for transcription and returns a complete MIDI draft.
- 03Review timing and dynamicsInspect the piano roll, correct errors, and export the result for your music software.

Straight answers
Before you upload
Is this converter really free?
Yes. You can run up to 10 conversions per UTC day without creating an account or entering payment details.
Do you limit the result to 30 seconds?
No. We process and return the full uploaded track within the product limit of five minutes and 50MB.
How long are my files kept?
The uploaded source is removed after the provider reaches a terminal state. The MIDI result and job record expire within 24 hours. Your browser keeps a local copy of the source only so you can replay it on the result page.
Is WAV always more accurate than MP3?
Not automatically. WAV preserves more source detail, but a clean performance and a clearly audible instrument matter more than the container format alone.
Should I upload a mono or stereo WAV?
Either is accepted. Use the version in which the instrument or melody you want is easiest to hear.
Can I convert a WAV mix with several instruments?
You can upload it, but competing instruments and effects make note attribution harder. Isolated or clearly separated parts are more useful starting points.
