GVST GSnap vs Performative Ear

GVST GSnap is a free pitch-correction effect plug-in for VST hosts, intended for music production, broadcasting, and audio editing. It offers fixed-scale correction based on selected notes, or MIDI correction controlled in real time. In MIDI mode, audio notes move to the nearest note currently held on a controller or specified in a sequence. A visual display distinguishes source pitch in red from corrected pitch in green. Controls cover detection range and gate, correction amount and timing, pitch bend, vibrato, and tuning calibration. GSnap is designed for monophonic material, such as a vocal melody or instrument line, rather than chords or rhythm. It runs on Linux, macOS, and Windows, with documented 32-bit and 64-bit versions for Windows and Linux. It cannot run by itself and needs a VST host; Audacity is one possible host. Installation generally requires extracting the ZIP archive and copying the plug-in into a folder scanned by the host, as there is no automated installer. The plug-in is supplied at no cost and may be used for private or commercial audio work.

Performative Ear is a paid pitch-correction plug-in designed for low-latency singing on Windows and macOS. Performative Ear listens to a song and sends its detected key to the pitch-correction plug-in automatically, while passing audio through unchanged without files or network use. Four correction modes are listed: Live at 1.3 ms, Crisp at 18 ms, Voice at 25 ms, and Full at 40 ms. Users can choose chromatic, major, or minor scales and toggle notes to create a custom scale. The maker lists tested support for Ableton Live 11 and 12, Cubase, FL Studio, Fender Studio Pro, Bitwig Studio, REAPER, Audacity, and GarageBand. Formats include VST3 and CLAP on Windows x64 and macOS Universal, plus Audio Unit on macOS. The price is $199 as a one-time purchase, with no free plan and a free Windows demo. One license supports three active machines.
