PitchNet

PitchNet is a free, open-source vocal tuning plugin from Session Loops. It detects pitch as editable notes and uses AI resynthesis for natural-sounding corrections, with ARA support in compatible DAWs on Windows, Mac and Linux.

PitchNet is a vocal pitch correction plugin from Session Loops that rebuilds tuned vocals through AI resynthesis rather than only stretching and warping the recorded waveform. The aim is a more natural result when notes are moved, with smoother transitions between pitches and a tone that stays closer to a real performance. It is distributed free of charge and the source code is published on GitHub. In use, the plugin detects the pitch of a vocal and shows it as editable note regions. Producers and engineers can adjust intonation or reshape a melody by working with notes instead of hunting through raw waveforms. The homepage demonstrates the idea with A/B clips in which an original vocal is shifted up three semitones and compared against the same shift made in Melodyne, so a buyer can judge the difference by ear before installing anything. PitchNet supports ARA in compatible DAWs. With ARA, the plugin follows the host timeline, analyzes audio faster and keeps tuning work tied to the arrangement, which avoids the bounce-and-reimport routine older tuning plugins often require. Installers are offered for Windows (VST3 and AAX), macOS (VST3, AU and AAX, as a Universal Binary for Apple Silicon and Intel) and Linux (VST3 and a standalone app). The listed requirements include 8GB of RAM at minimum with 16GB recommended, about 500MB of disk space, and a dedicated GPU recommended on Windows. The audience is music producers, mixing engineers and home-studio vocalists who want note-based tuning without paying for a commercial suite. Within the pitch correction field, it sits as a free alternative to established editors such as Melodyne, trading a long track record for a resynthesis approach and an open codebase. The tool is still on a 0.x release line (version 0.7.2 at the time of the listing), so it suits users comfortable with an actively developing plugin. Session Loops also sells a subscription covering its other products, VocalNet and DrumNet, and points to it as a way to support PitchNet's development. Feedback and help are handled through a Discord community.
