MeldaProduction MAutoPitch vs Soundtoys Little AlterBoy

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.
