Auburn Sounds Graillon 3 vs MeldaProduction MAutoPitch

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.

MeldaProduction MAutoPitch is a free automatic tuning and pitch-correction plugin for vocals and other monophonic instruments. It provides formant shifting and stereo expansion, and offers eight A-to-H setting slots; an X-Y pad can morph among the first four. MIDI controllers and keyboards can adjust parameters in real time, with MIDI learn. Automatic gain compensation and a safety brickwall limiter keep output below 0 dB. The plugin supports mono, stereo, mid-side, separate left/right or mid/side, up to 8-channel surround, and up to 64-channel ambisonics. It processes audio at 64-bit and the maker says it handles any sampling rate. MAutoPitch runs on 64-bit Windows and Mac through VST, VST3, AU, and AAX interfaces, with support for all major hosts on those systems. It is included in the free MFreeFXBundle of 38 audio effects. Installation uses MPluginManager. The maker says licence-file activation needs neither a dongle nor internet access.
