Piano Audio to MIDI Converter

MIDI (Musical Instrument Digital Interface) is a standard file format for representing musical performances in terms of notes, timings, and velocities. Unlike digital audio, which only stores information describing waveforms, MIDI gives you complete control to edit the pitches and timings of every note.

MIDI gives you so many options. Have you ever played one blatantly wrong note on a piano recording? With MIDI, just slide the note to the correct pitch. Did you play it too slowly? With MIDI, change the tempo with one click. Can't afford that 9-foot Steinway you've always dreamed of? No problem. Play your MIDI file through inexpensive virtual instrument software to sound like you recorded on a $300,000 instrument.

As you can imagine, converting raw audio (such as wav or mp3 files) into editable MIDI files is nontrivial. We build upon decades of AI and machine learning research to provide a tool that gives near-perfect transcriptions of piano recordings. We couple GPU-accelerated neural networks with advanced signal processing techniques to detect notes, velocities, and timings from your piano recordings. Then we package this information into a MIDI file that you can save and edit on your own computer.

For piano, yes. Most generic converters are trained on all instruments and compromise on every one. Ours was trained exclusively on a large custom dataset of piano recordings we created, so it handles velocity, sustain, pedaling, and fast passages with accuracy that generic tools can't match.

BPM stands for "beats per minute" and is a measure of tempo. In most cases, you can stick with the default of 120 BPM, since DAWs default to 120 BPM unless otherwise specified (see page 143 of the MIDI 1.0 specification). If your project uses a different BPM, make sure to specify it inside the dropzone above before uploading your audio file. This will ensure that your MIDI file lines up with the audio in your project. If your project switches between multiple BPM values, make sure to turn off time stretching and/or use a sample-based MIDI track (not tick-based) to ensure the MIDI timing matches your original audio.

You can upload an audio file up to 100 MB in size. If your file is too large (often the case with wav files), you can use an online converter such as cloudconvert to first convert to mp3 for a much smaller file size. Free users receive the first 30 seconds converted at no cost. Upgrade to a Flex or Pro plan to convert up to 30 minutes per file.
