Q3D is a detailed emulation of the NTI Nightpro EQ3D rack mount equalizer, designed to deliver precise tonal shaping across six distinct bands. It features an intuitive user interface that simplifies the process of adjusting frequency and boost settings, making it suitable for a wide range of audio applications. Notably, one of the bands called AIR is a high shelf filter with adjustable frequency and boost, providing enhanced clarity and brightness to mixes. This equalizer has been trusted in professional environments, especially for vocal processing, contributing to numerous well-known recordings.

The six-band configuration includes four peaking bands with center frequencies at 10 Hz, 40 Hz, 160 Hz, and 650 Hz, each offering a broad 2.5 octave bandwidth for smooth and natural adjustments. The fifth band is a high-frequency shelving filter set at 2.5 kHz, perfect for controlling the upper mids. The distinctive sixth band, known as the AIR band, is a high-frequency shelf that allows boost only, with five selectable cutoff frequencies ranging from 2.5 kHz up to 40 kHz. This setup allows for detailed control over the high-end spectrum, enhancing presence and airiness without harshness.

Engineered for efficiency, Q3D incorporates a proprietary topology that ensures low latency, minimal noise, and a wide dynamic range, supporting sample rates up to 384 kHz. The plugin offers smooth and click-free parameter adjustments, providing a seamless user experience during mixing and mastering. Its high processing efficiency makes it a reliable tool for both studio and live sound environments, delivering professional-grade equalization with precision and clarity.
