Quantum-Music – Mastering LPEQ x32 VST WiN [free]

Quantum-Music’s Mastering LPEQ x32 is a linear-phase equalizer built specifically for mastering work. Developed with the Electrical Engineering Department at École polytechnique de Montréal, it aims for maximum transparency using signal processing theory. It supports sample rates from 44.1 kHz to 96 kHz and bit depths from 16 to 32 bits, covering the full 20 Hz–20 kHz range. You get left/right or mid/side operation, peak detection, and ±6 dB gain across 8 mono or 4 stereo channels. There are fixed 30 Hz low-cut and 18 kHz high-cut filters, solo buttons per channel, separate gain knobs for each channel plus an input gain control, and peak metering with VU and peak indicators. True linear-phase processing and innovative Bandwidth and Precision controls let you shape your master with precision. It’s a Windows VST plugin (9 MB) suited to hobby producers using FL Studio, Ableton, or Logic who want a clean, transparent EQ for final mixes. No fluff—just a focused tool for mastering-grade equalization.
