Features
Professional room acoustic correction powered by advanced signal processing
Professional-Grade Measurement
Capture your room's complete acoustic signature using Maximum Length Sequence (MLS) technology. Multi-position averaging ensures accurate, repeatable results.
- MLS test signal for precise impulse response extraction
- Support for 1-9 measurement positions
- Automatic averaging across positions
- Calibration file support for major microphone brands
Hybrid FIR+IIR Correction
Advanced hybrid filter architecture combines FIR precision for mid/high frequencies with IIR efficiency for bass—optimal correction across the entire spectrum.
- 4,096 FIR taps for mid/high frequency precision
- Up to 31 IIR bands for efficient bass correction
- Smooth 200-300Hz crossover region
- Linear phase preservation in critical frequencies
Real-Time Visualization
See your room's acoustic behavior with spectrum analyzers, waterfall displays, phase plots, and impulse response views.
- Frequency response with adjustable smoothing
- Real-time spectrum analyzer with statistics
- Waterfall/spectrogram display
- Phase and impulse response visualization
Multi-Channel Support
From stereo to Dolby Atmos 7.1.4, handle up to 34 channels with independent correction for each.
- Stereo through 7.1.4 Atmos configurations
- Per-channel independent correction
- Subwoofer integration optimization
- Channel-specific delay alignment
Customizable Target Curves
Choose from professionally-designed presets like Flat, Harman In-Room, or House Curves. Create your own to match your preference.
- Flat reference for mixing/mastering
- House Curves for relaxed listening
- Harman In-Room research-based curve
- Custom curve editor with point control
Native macOS Experience
Built exclusively for macOS with SwiftUI. Seamless integration, native performance, and full Apple Silicon optimization.
- Universal binary for M1/M2/M3 and Intel
- Native SwiftUI interface
- System-wide or per-app processing
- Minimal CPU usage in background
