Piano Transcription Tool: Audio->MIDI

This tool converts audio recordings of piano performances to MIDI files.

It uses a deep learning model to detect piano notes in audio and transcribe them to MIDI format.

It is useful if you have some piece you want to learn, that they have not provided the sheet music for

Once you have the MIDI it is easy to turn into sheet music. Or drag into PianoTeq and learn it that way

Features

Audio to MIDI conversion
Support for uploaded audio files

Usage

Docker

Two Docker configurations are available:

Standard Version (with GPU support)

# Windows
run_docker.bat

# Linux/Mac
bash run_docker.sh

Minimal Version (CPU-only)

# Windows
run_docker_minimal.bat

# Linux/Mac
bash run_docker_minimal.sh

This builds a smaller image but only supports CPU processing, which is slower for transcription.

Direct Python Installation

Run directly with Python after installing the requirements:

pip install -r requirements.txt
python app.py

UI

Drag your MP3 or WAV file into the "Upload an audio" component.

Click Transcribe

You should get an output.mid file in the "Download MIDI" component

Note the jazz_sample.mp3 example, a nice 13 second jazz piano clip
