MStereoProcessor is an advanced multi-band stereo analyzer and enhancer. It lets you look at and listen to the stereo field and its mono compatibility, ensure your recording is truly placed into the center, and widen, shrink and excite stereo on separate bands.

Features:

• Global panorama, widening and exciting - you can modify the panorama and widening of the signal itself. The algorithm is totally transparent and mono compatible. You can apply a broadband exciter to improve clarity of each band.
• 4 bands with separate widening and exciting - while it is often desired to have bass stereo field minimal as opposed to treble, MStereoProcessor lets you process all bands separately. You can modify the stereo field from mono to 200% increase and even perform delayed stereo enhancement. Both algorithms are fully transparent and mono compatible. You can apply an exciter to improve clarity of each band.
• 2D stereo field analyzer and channel peak meters - integrated analyzers give you an accurate view of the output stereo profile, which you can use to ensure the recording is accurately wide and has correct direction.
• Mono/stereo field check - you can easily check if your recording is mono compatible and what the stereo content actually is.
• Mute and solo for each band - you can always listen to each band and check that each spectral part of the recording is perfect.
• Advanced and easy-to-use user interface - you can easily change all values and gain maximal accuracy using textual editing.
• Adjustable up-sampling 1x-4x to minimize aliasing and get even more clear sound.
• Global preset management - using a title button you can save your settings, which are shared on the computer, so you can easily access them in other songs.
• Full automation.
