MStereoProcessor by MeldaProduction is an advanced multiband stereo analyzer and enhancer plugin designed primarily for mastering and final mix refinement. It splits your audio signal into four independent frequency bands, allowing you to sculpt the stereo image, depth, and space of a track with high precision. Core Features
Multiband Processing: Splits the audio into four separate bands (typically bass, low-mids, high-mids, and highs) with custom crossover points.
3 Crossover Modes: Offers choices like analog (minimum phase) and linear phase crossovers to optimize for phase accuracy or low latency.
Built-in Harmonic Exciter: Each of the four bands includes its own exciter to inject saturation and harmonics, adding clarity, warmth, or top-end sparkle.
Stereo Field Visualization: Features an integrated stereo profile analyzer and peak metering to check mono compatibility and prevent phase cancellation.
Melda Ecosystem Perks: Includes 16x upsampling, automatic gain compensation (AGC), a safety limiter, and a highly customizable GPU-accelerated interface. Common Workflow Applications 1. Cleaning and Anchoring the Low End
The plugin is highly favored for mono-ing the bass. In modern mixing, low frequencies (below 100–150 Hz) are kept strictly in mono to preserve punch and prevent phase issues on club sound systems. MStereoProcessor lets you drop the stereo width of the bottom band down to zero while keeping the rest of the mix wide. 2. Clearing Midrange Muddiness
The low-mid band often accumulates muddy overlapping frequencies. Engineers use this tool to gently pull back the volume or narrow the stereo image on this specific band, carving out space for vocals and main instruments to sit clearly in the center. 3. Creating Top-End Air and Shimmer
By expanding the high-mids and high bands, you can push cymbals, background vocals, and synth pads further to the sides of the stereo field. Combining standard widening with the built-in high-frequency exciter gives a final master an open, “airy” soundscape. Technical Compatibility MStereoProcessor walk through
