Klangio Transcription Plugin
What Klangio Transcription Plugin is
Klangio Transcription Plugin converts music audio into MIDI for multiple instruments from inside a digital audio workstation. Add an audio file, and it can identify up to eight instrument types, including vocals, piano, drums, bass, guitar, synthesizer, strings, and wind instruments. Its output contains unquantized melodies, chords, and rhythmic patterns that you can return to your DAW. The plugin is available as VST3, AU, and a standalone application; Klangio says it works with all DAWs. A free preview lets you view and play generated MIDI before upgrading, with no usage cap stated. Audio processing requires an active internet connection because audio is sent to Klangio AI and the resulting MIDI returned to your device. Export is limited to unquantized MIDI; other note formats are available through Klangio Transcription Studio. Results can vary with audio quality, instrument count, mixing, and effects. Plans include a free option and paid plans from $8.49/mo (annual).
