MAutoPitch is a simple automatic pitch correction plugin designed for vocals and other monophonic instruments. Besides its main purpose of making the audio more in-tune, MAutoPitch provides also a few creative such as formant shift and stereo-expansion. It is quick, easy to use and free!

M/S, single channel, up to 8 channels surround processing - our plugins can handle not only mono and stereo signals, but also mono/stereo encoding, separate channels and encodings, and up to 8 channels of surround audio, which makes them ideal for audio production for movies, games etc.
Full randomization - using a single button you can generate completely new settings. By clicking the button you can walk through the billions of possible settings and find the best one for you! And if that's too much, you can just hold ctrl and MAutoPitch will only slightly modify existing settings.
Extremely advanced and easy-to-use user interface - our products are always designed to enhance the workflow. You can easily change all values, fine-tune each control in multiple ways. Easy orientation in a standardized GUI, textual editing and smooth visualization with almost unlimited zooming are standard in all of our plugins. Moreover our plugins are the world first (and still the only ones), which support resizable and stylable GUI's.
MIDI controllers with MIDI learn - you can map any parameter to any MIDI controller or MIDI keyboard and control it realtime or record and automate it.
Very fast, optimized for SSE and SSE2 processors.
Global preset management and online preset exchange - using a title button you can save your settings (which are shared on the computer) so you can easily access these in other songs. Moreover all plugins can automatically share your presets and download presets of other users from our servers (if this feature is enabled). We are building a community and you can be a part of it!
Fully automatable.
