Key Features

Advanced acoustic analysis and hybrid filter technology to transform any listening space into a precision monitoring environment.

  • Professional-Grade Measurement

    Capture your room's complete acoustic signature using Maximum Length Sequence (MLS) technology. Multi-position averaging ensures accurate, repeatable results.

  • Hybrid FIR+IIR Correction

    Advanced hybrid filter architecture combines FIR precision for mid/high frequencies with IIR efficiency for bass—optimal correction across the spectrum.

  • Real-Time Visualization

    See your room's acoustic behavior with spectrum analyzers, waterfall displays, phase plots, and impulse response views. Verify corrections are working.

  • Multi-Channel Support

    From stereo to Dolby Atmos 7.1.4, handle up to 34 channels. Perfect for home theaters, music production studios, and audiophile listening rooms.

  • Customizable Target Curves

    Choose from professionally-designed presets like Flat, Harman In-Room, or House Curves. Create your own target curve to match your preference.

  • Native macOS Experience

    Built exclusively for macOS with SwiftUI. Seamless integration with your Mac, native performance, and full Apple Silicon optimization.

FAQ

Room correction is a technology that measures how your room affects sound and creates digital filters to compensate. Every room has acoustic problems—reflections, standing waves, and absorption—that color the audio you hear. Correction filters counteract these effects for more accurate sound reproduction.
