A2M (Audio To MIDI) is a simple desktop tool for transcribing local audio files into MIDI files with one click.
It is designed primarily for piano music transcription and works best on solo piano recordings.
Using A2M is straightforward:
Select an audio file, click Convert, and the application generates a MIDI file automatically in your Downloads/A2M folder.
All processing is done locally on your device, no uploads, no accounts, and no telemetry.
The app runs on CPU by default, with optional NVIDIA GPU acceleration for faster conversions.
