Auburn Sounds Graillon 3 vs Softube Vocal Tuner

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.

Softube Vocal Tuner is a real-time vocal pitch-correction plug-in for macOS and Windows. It runs inside a DAW host that supports AU, VST, VST3 and/or AAX plug-ins. Classic correction targets a traditional sound, while Modern correction is designed to preserve vocal formants. Subtle/Hard changes correction speed, and Natural/Robotic changes correction on note transitions. Pitch and formant shifting can work independently or together. Octave-up and octave-down layers have separate gain controls, and Tone Enhance adds processing. Low Latency mode is intended for tracking and live performance, with reported latency under 1 millisecond. Metering and visualizations show the input signal and processing effect. The plug-in supports MIDI pitch control and a 12-semitone pitch-shift range, but has no scale or key detection. It costs 199.00 EUR once, includes a 20-day trial and three activations, and requires Softube and iLok accounts plus internet access.
