Audio to MIDI Converter

This tool converts audio recordings into MIDI data, enabling rapid transcription and flexible musical analysis. It ingests common audio formats (WAV, MP3, FLAC) and outputs a standard MIDI file. Conceptually, the process decomposes the audio into time-stamped note events, detects onset timings, estimates pitch per frame, and constructs MIDI messages with velocity and duration. It supports monophonic and polyphonic scenarios, with optional instrument mapping and velocity smoothing for more natural playback. The result is a MIDI track suitable for import into DAWs or score editors, with an accompanying tempo map when available. Users benefit from faster transcription, easier arrangement, and the ability to experiment with alternative orchestrations without re-creating performances from scratch. Core features include robust onset detection, pitch estimation, tempo tracking, and reliable MIDI export; optional advanced features cover quantization, groove templates, and batch processing. Use cases include turning a reference performance into sheet music, generating backing tracks for rehearsal, or extracting melodic material for educational analysis. The tool emphasizes accuracy under varying audio qualities and provides confidence scores to indicate transcription reliability. It differentiates itself by combining polyphonic handling with tempo mapping and straightforward MIDI export, enabling efficient workflow integration for composers, educators, and producers.
