E-HighEndClassicEQ300 (Windows-G)

A JSFX plugin for REAPER that faithfully recreates the Pultec-style EQ curve of vintage high-end EQs by applying Boost and Cut in parallel. Whether you are adding air to vocals, brilliance to your cymbals, or lifting the top end of your overall mix, this plugin lets you sculpt high frequencies using the classic high-end EQ curves with modern precision. By leveraging parallel Boost/Cut processing and carefully selected Q-factor values, it achieves that pultec-style high-end enhancement without introducing phase artifacts. It’s a must-have for mixing and mastering. It features:

* 3 High-End EQ Modes: Choose between three Pultec-inspired EQ modes:

1. Classic Bell & Shelf (Pultec-style): Combines a bell filter for boosting and a shelf filter for cutting in parallel, ideal for that vintage-style high-end shimmer.

2. Classic Dual Shelf (Pultec-style): Uses two shelf filters for Boosting and Cutting in parallel, perfect for adding clean high-end presence and air.

3. Classic Dual Shelf + LPF (Pultec-style): Adds a user-adjustable low-pass filter after the dual shelf stage, great for taming unwanted harshness or simulating vintage high-end roll-off.

* Channel Modes: Apply equalization in Stereo, Mid, or Side modes to precisely enhance the airiness or sparkle where it matters most.

* Continuous Frequency Control (1kHz–20kHz): Unlike vintage pultec EQs with fixed bands, you can adjust the frequency from 1kHz to 20kHz, this lets you precisely target the high-frequency range to enhance or tame air or brilliance.

* Independent Boost and Cut Controls: Independently control the boost (0-20 dB) and cut (0-20 dB) for precise high-end tonal shaping.

* Dedicated LPF Frequency Slider (1kHz–21kHz): When in "Classic Dual Shelf + LPF" mode, you can adjust the low-pass filter frequency from 1kHz to 21kHz, to roll off unwanted high frequencies.

* Dry/Wet Mix Control (0–100%): Blend your processed signal with the original dry signal for parallel processing.

* Zipper Noise-Free: Advanced smoothing ensures no zipper noise during slider automation and real-time adjustments.

* Light on CPU: Its highest CPU usage hovered around 0.5% on a low-powered PC.
