Linear-Phase Equalization
Mastering-grade parametric EQ with zero phase distortion. The reference standard trusted by mastering engineers worldwide. Three distinct processing philosophies — one uncompromising commitment to transparency.
MAAT Inc. Partnership
Since 2017Algorithmix PEQ algorithms are licensed to MAAT Inc. for modern 64-bit, cross-platform versions. Each Algorithmix PEQ has a corresponding MAAT product — thEQred, thEQorange, and thEQblue — bringing our acclaimed linear-phase processing to macOS, Windows, and Linux with native Apple Silicon support.
PEQ Red
Continuous Slope Filter with 0-24 dB/Oct slope control. Frequency domain processing with unmatched precision. The premium choice for mastering engineers.
PEQ Orange
Time domain processing with analytical precision. The "surgical" choice for detail-oriented mastering. When every fraction of a dB matters.
Classic PEQ Blue
12 analog EQ emulations in one plugin. 10 serial + 2 parallel EQ types modeled from classic hardware. Vintage character meets linear-phase precision.
