Auburn Sounds Graillon 3 vs Performative Ear

Auburn Sounds Graillon 3 is a live vocal processor and pitch-correction plug-in for shaping standard or edgy vocals. Its pitch tools include pitch shifting, formant shifting, pitch correction, and three engines: G2, G3, and I1. A compressor, gate, chorus, preamp, and bitcrusher are built in; Auburn Sounds says the vocal-tuned effects add no latency. The free edition includes the pitch features and effects. The Full Edition adds Pitch-Tracking Modulation, keyboard tuning, a vocal doubler, and 20 more presets. Graillon supports CLAP, VST3, VST2, Audio Unit v2, AAX, LV2, and FLP formats on Windows 7 or newer, macOS 10.15 or newer, and Ubuntu 22.04 or newer. Listed host software includes Pro Tools, Cubase, Logic, Live, and FL Studio. The Full Edition costs $29.00 USD or more as a one-time purchase. The maker states there is no subscription or update fee. Session compatibility is maintained across minor version changes, but may break across major changes.

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.
