A2M (Audio to MIDI) is an open-source Windows application for converting piano recordings into editable MIDI files. It estimates notes, timing, velocity, sustain, and soft-pedal events, with the best results obtained from clean solo piano recordings.
Choose an audio file, select CPU or a CUDA/DirectML mode, and click Convert to MIDI. The generated file is saved to Downloads/A2M by default, or to a custom folder selected in Settings.
Audio analysis is performed locally. Source recordings are not uploaded, and no account is required. Network access may be used for requested downloads and update checks when enabled.
CPU processing is available by default. Optional GPU acceleration can reduce processing time on compatible hardware.
