EQ Sketch
With EQ Sketch, you can draw an EQ curve in one motion, quickly setting up initial bands, LP/HP filters, and bell filters. This speeds up workflow and helps create a starting point for mixing. Combined with the Instance List, it becomes a powerful time-saving tool.
Dynamic EQ
Any Pro-Q 4 band (Bell or Shelf) can be made dynamic, with perfect analog matching and Linear Phase mode support. Attack, release, and knee settings adjust dynamically based on the processed audio, ensuring natural compression and expansion.
Spectral Dynamics
Unlike traditional dynamic EQ, Spectral Dynamics processes specific frequencies within a band instead of the entire band, allowing for subtle and targeted adjustments to problematic frequencies.
Instance List
Pro-Q 4 allows you to control all instances in your session from a single interface, making it easier to manage EQ settings across multiple tracks.
Piano Display
The Piano Display lets you adjust band frequencies using musical notes. Click a note to quantize the frequency, or drag to adjust while keeping it aligned to musical pitch.
Surround and Dolby Atmos
Pro-Q 4 supports surround and immersive audio formats up to 9.1.6 Dolby Atmos. The interface adapts automatically to multi-channel formats, and the Stereo Placement button provides advanced speaker targeting options.
EQ Match
EQ Match lets you compare and match your audio spectrum to a reference signal. This feature is accessible via the Instance List, enabling quick sound matching.
Band Controls
Interactive EQ band controls appear dynamically for easy adjustments. This floating control system streamlines workflow and enhances precision.
Full Screen Mode and Interface Scaling
Pro-Q 4 offers a full-screen mode for precise EQ adjustments, along with smooth interface scaling for better usability on different screen sizes.
A top-quality EQ plug-in with perfect analog modeling, dynamic EQ, linear phase processing, and a gorgeous interface with unrivaled ease of use.
