Field notes
The workbench accepts both audio and video, then presents a waveform, pitch roll, keyboard panel, and timeline controls for detailed practice. Its speed range runs from 5% to 400%, while transpose controls cover ±24 semitones with cent-level adjustment. Users can save markers, loops, and settings locally, reopen a last file up to 100 MB, or export processed WAV audio.
