WIDI Audio To MIDI Audio Unit is designed for real-time Audio to MIDI transcription. Use it to control any MIDI instrument with live "analog" instrument or to transcribe pre-recorded audio tracks.
The unit takes an audio channel as input and detects musical notes. Notes are converted to MIDI and sent to any MIDI Output Device (including virtual devices for routing MIDI back to AU host), or saved as a MIDI file with a simple MIDI recorder. The spectrum window displays streaming spectrogram in real-time with recognized notes above it. Also, the plugin recognizes chords and displays chord name at the top of the spectrogram window. It is possible to control the delay of chord indication. Adjustable recognition parameters allow improving recognition quality.
With WIDI Audio To MIDI AU you can transcribe pre-recorded audio tracks as well. Tweaking recognition parameters takes effect instantly, allowing to enhance transcription accuracy on the fly.
Most of AU-enabled music production systems for macOS are supported. Both 32bit and 64bit versions are included.
You need to have some Audio Unit Host to run this plugin. See WIDI Recognition System if you need a standalone application.
Trial version allows evaluation of all plugin operating modes, but recognition process interrupts each 15 seconds and spectrogram window displays "Evaluation" message instead of the actual spectrogram during this period.
You may purchase WIDI Audio To MIDI AU with many different methods. Purchasing removes limitations of trial version and allows you to receive priority technical support via email.
