PSP Tilt-Q is a modern tilt and contour equalizer designed for fast, musical tonal shaping. Instead of surgical moves, it encourages broad, meaningful adjustments that naturally glue tracks together and bring clarity, depth, and balance to your mixes.

With a tilt EQ, contour (loudness) control, and high-quality high- and low-pass filters, each offering multiple response characteristics, PSP Tilt-Q adapts easily to tracks, buses, and full mixes. Its sound remains smooth and cohesive even when used across many channels.

Powered by 64-bit double-precision processing and PSP’s proprietary soft saturation, PSP Tilt-Q delivers musical results without harshness - helping your mix feel open, connected, and effortless.

Key Features of PSP Tilt-Q:

Tilt Equalizer with Three Characteristics
Musical tilt EQ offering three distinct curve shapes, allowing you to quickly rebalance lows vs highs while choosing between classic, low-high focused, or mid-centric behavior.

Contour (Loudness) Equalizer with Three Characteristics
A loudness-style EQ designed to enhance lows and highs while shaping the midrange, with three selectable response characteristics inspired by classic hardware loudness designs and soft curve equalisers.

High-Pass & Low-Pass Filters
Independent HPF and LPF with selectable 6, 12, or 24 dB/octave slopes for precise low- and high-frequency range control.

Flexible Channel Processing
Apply processing to Left, Right, Mid, Side, or full stereo signals—ideal for stereo imaging, mastering, and corrective EQ work.

FAT Double Sampling
Automatic oversampling for lower sample rates (below 50 kHz) ensures consistent, high-quality processing across all supported sample rates.

64-bit Double-Precision Processing
Ultra-high-accuracy internal processing minimizes cumulative errors, preventing noise buildup and preserving natural filter behavior.

Second-Generation Output Saturation (SAT)
Optional soft saturation at the output stage adds smooth analog-style drive while protecting against digital clipping.

Integrated PSP Spector PSPEC-31 Analyzer
Built-in 31-band spectrum analyzer with bar or curve display modes, allowing real-time visualization before or after EQ processing.

Intuitive, Console-Style Interface
Designed for fast, musical decisions with minimal controls—ideal for mixing, mastering, and tone shaping without overthinking.
