MP3 to MIDI Converter Online

You use this MP3 to MIDI converter when a quick idea lives only in a phone recording and you need real notes to continue working in your DAW. It lets you convert MP3 to MIDI online for free with AI-assisted audio analysis, without replaying the part or rebuilding the melody by ear.

Step 1. Upload your MP3 file. Start by selecting your MP3 recording when you want to turn a short audio idea into editable notes.

Step 2. Convert MP3 to MIDI automatically. Once the file is uploaded, the AI engine analyzes pitch and timing automatically and converts MP3 to MIDI without requiring manual adjustments.

Step 3. Download MIDI file. When the conversion finishes, download the MIDI file and open it directly in your DAW or notation software.

More Accurate Note Detection for Single-Instrument Recordings

When your MP3 contains one clear instrument, such as a piano or guitar line, AI-based note detection produces more accurate pitch and timing, so you spend far less time fixing wrong or missing notes after MP3 to MIDI conversion. It is less reliable for full mixes or songs with multiple overlapping instruments.

MIDI Files That Open Cleanly in Your DAW

AI-assisted audio analysis helps reduce fragmented and incorrect notes before export, so your MIDI file opens cleanly and stays easy to edit.

What Is an MP3 File?

An MP3 file is a compressed audio format that stores real sound, such as piano, guitar, vocals, or any recorded performance. You use an MP3 to MIDI converter when your idea exists only as audio and you want to turn that sound into editable notes.

What Is a MIDI File?
