01Overview

PSP Tilt-Q is built around two equalizer styles: a tilt EQ that shifts the balance between lows and highs, and a contour EQ that lifts the lows and highs while shaping the midrange. Each has three selectable characteristics. Independent high-pass and low-pass filters with 6, 12 or 24 dB/octave slopes handle range control. The plugin is part of PSP Audioware's EQ line and uses a console-style layout with a small set of controls.

Tilt and Contour Curves for Tone Balance

The tilt section rebalances low and high frequencies with three curve shapes, letting you choose between a classic tilt, one focused on lows and highs, or one centered on the midrange. The contour section works as a loudness-style EQ. It enhances the low and high ends and shapes the mids, with three response characteristics that the developer describes as inspired by classic hardware loudness designs and soft curve equalizers.

Both sections are meant for quick broad adjustments rather than surgical cuts, which suits mix bus and mastering moves.

Filters, Channel Routing and Metering

Independent high-pass and low-pass filters offer selectable 6, 12 or 24 dB/octave slopes for controlling the bottom and top of the range. Processing can be applied to the left, right, mid, side or full stereo signal, which is useful for stereo image adjustments and corrective EQ on specific channels.

An integrated PSP Spector PSPEC-31 analyzer displays a 31-band spectrum in bar or curve mode, before or after EQ processing. An optional output saturation stage adds soft drive and guards against digital clipping.
