MP3 source profile
Compression matters less than musical separation.
- What MP3 preserves
- A good MP3 keeps the rhythm, melody, and note attacks needed for a useful transcription draft.
- What can get blurred
- Low bitrates and repeated exports can soften transients and add artifacts around sustained notes.
- Best use here
- Start with demos, voice notes, isolated parts, or references where the target line is easy to hear.

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.
Does MP3 compression affect the MIDI result?
It can. A higher-bitrate MP3 with a clear lead part usually gives the model more useful detail than a heavily compressed copy.
Can I convert a finished song from MP3?
Yes, if you have permission to process it, but a dense mix may produce overlapping or incomplete notes. Use the result as a transcription draft.
What should I do after converting an MP3?
Open the generated MIDI in the browser editor to remove stray notes, adjust timing, and export a file for your DAW.
