MeldaProduction MAutoPitch vs Performative Ear

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.

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.
