+description: A five-band stereo imaging processor using proprietary LCR
+  separation for natural, transparent stereo width control in mixing and
+  mastering.
+details: |-
+  DeeMultiWider is a stereo imaging processor that employs a proprietary LCR separation method distinct from conventional M/S processing. The plugin extracts shared components between left and right channels while preserving non-common components in their original positions, enabling natural, transparent control over stereo width without the phase artifacts typical of M/S methods.
+
+  The frequency spectrum divides into five independent bands (LOW, LOW-MID, MID, HIGH-MID, HIGH), each with adjustable STEREO SIDE control. Users can maintain a solid low end while widening mid and high frequencies. Crossover frequencies are adjustable, and processing uses 64-bit double-precision internally.

 details: |-
   DeeVocalTools is an all-in-one vocal processing plug-in that bundles four essential vocal tools into a single interface: a de-esser for reducing harsh sibilance, a multiband compressor for evening out vocal loudness in a balanced way, a vocal EQ for adjusting high frequencies, and a pitch-tracking doubling effect for adding the thickness of layered recordings.
