WIDI Audio To MIDI VST review
A focused VST plugin for converting live or recorded polyphonic audio into MIDI.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WIDI Audio To MIDI VST is a desktop plugin for musicians, producers, and composers who need to convert live or prerecorded audio into MIDI within a compatible VST host. It recognizes polyphonic notes and chords, displays a spectrogram and detected notes, and sends MIDI to the host or a system MIDI device. Its built-in recorder can also save MIDI files, making it suited to DAW-based transcription workflows rather than standalone use.
The plugin’s strongest fit is inside an established desktop music-production setup. It supports Windows and macOS, with listed plugin plans for both Windows and Mac OS X. Each plan includes a VST plugin with 32-bit and 64-bit versions. Integrations include Steinberg Cubase, Cakewalk Sonar, Plogue Bidule, and Ableton Live. Recognition can be adjusted through polyphony and sensitivity parameters, which gives users control over how the software interprets complex audio. Chord detection, MIDI export, and real-time processing make it more capable than a tool limited to offline note extraction.
The trade-off is a narrow, host-dependent workflow. WIDI Audio To MIDI VST is not standalone software, so it is a poor fit for users who want to import audio into a self-contained application without a VST host. Its output format is MIDI, with no other output formats listed. The product is paid, has no free plan, and the trial interrupts recognition every 15 seconds. The listed starting price is 49.90, while payment method, location, and applicable sales tax can affect the final amount. Choose it for real-time MIDI conversion inside a supported DAW; choose an alternative if standalone operation or broader export is essential.
