Perceptual Spectrum Balancer

 Perceptual Spectrum Balancer

An equalizer that uses psychoacoustic models to balance audio based on human perception rather than raw frequency analysis. It automatically corrects spectral imbalances using Bark scale analysis, inter-frequency masking detection, and ISO 226 equal-loudness curves.

The tool offers three intelligent modes: Clarity Mode reduces midrange masking for vocals and instruments, Full Balance targets a perceptually neutral spectrum, and Low-End Control corrects energy buildup below 200Hz. Six macro controls—Clarity, Presence, Low-End, Tilt, Smoothness, and Strength—provide intuitive shaping without manual frequency adjustments.

Real-time analysis displays the spectrum on a Bark scale, showing original and processed signals side-by-side. Eight presets cover common scenarios from vocal enhancement to mastering. A transparent limiter and automatic gain compensation maintain output levels while preserving dynamics.

Suitable for mixing, mastering, and sound design, Perceptual Spectrum Balancer reorganizes frequency content using perceptual principles, reducing the need for manual EQ moves. Export processed audio at full quality with all settings applied.
