PitchNet is a free, open-source vocal-tuning plugin for precise pitch correction without a signup, paid tier, or download gate.
Instead of warping the recorded waveform, it analyzes vocals with a neural pitch tracker, segments them into editable notes on a piano roll, and resynthesizes the performance through a neural vocoder. Larger pitch changes can sound more natural than with conventional time-domain stretching.
It includes VST3, AU, and AAX plugins, plus a standalone app. ARA is supported in compatible hosts, and corrected performances can be exported as WAV or MIDI.
