DalEQ Core
Professional 8-Band Parametric Equalizer
A premium 8-band parametric equalizer with Zero-Delay Feedback filters, Linear Phase mode, real-time spectrum analyzer, Mid/Side processing, and Dynamic EQ. Variable slopes from 6-96 dB/oct. Free plugin.
What Makes It Special
8 Fully Parametric Bands
Each band independently configurable with frequency (20 Hz - 20 kHz), gain (±30 dB), Q (0.025 - 40), and filter type. 9 filter types including Bell, Shelves, Cuts, Notch, Bandpass, Tilt, and Allpass.
Zero-Delay Feedback Filters
TPT (Topology-Preserving Transform) filter design based on Vadim Zavalishin's methodology. Correct analog-like response, stable at high resonance, accurate near Nyquist.
Variable Slopes (6-96 dB/oct)
Low Cut and High Cut filters offer 8 slope options: 6, 12, 18, 24, 36, 48, 72, and 96 dB/oct. From gentle rolloff to near-brickwall filtering.
Linear Phase Mode
True linear phase FIR processing with zero phase distortion. Four quality levels (Low to Ultra) with automatic latency compensation. Perfect for mastering and parallel processing.
Real-Time Spectrum Analyzer
4096-point FFT with Pre/Post EQ toggle, channel selection (L/R/L+R/M/S), adjustable speed, 60-120 dB range, and pink noise tilt compensation.
Mid/Side Processing
Each band can operate in Stereo, Left, Right, Mid, or Side mode. Widen highs, tighten center bass, or fix balance issues with surgical precision.
