Room Correction

Features

Professional-grade tools for measuring, correcting, and perfecting your room acoustics

Measurement

Capture your room's complete acoustic signature with professional precision

MLS Test Signal

Maximum Length Sequence technology for accurate impulse response capture with excellent signal-to-noise ratio.

Multi-Position Measurement

Measure up to 9 positions per session with automatic averaging for a broader correction sweet spot.

Microphone Calibration

Import calibration files from UMIK, REW, Earthworks, Dayton Audio, and more for accurate measurements.

Quality Scoring

Automatic scoring (A-D grades) based on frequency response, RT60, modal distribution, and reflections.

Correction Engine

Hybrid FIR+IIR architecture for optimal correction across the entire frequency range

Hybrid FIR+IIR Engine

4,096-tap FIR filters for precise mid/high correction combined with 31-band IIR for efficient bass control.

Target Curve Presets

Choose from Flat, House Curve A/B, Harman In-Room, B&K Preference, or create custom curves.

Low Latency

20-80ms processing latency depending on configuration. Suitable for music, movies, and most gaming.

Real-Time Processing

Apply correction in real-time with Apple Silicon optimization for maximum efficiency.

Multi-Channel Support

Independent correction for every channel, from stereo to Dolby Atmos

Visualization

Comprehensive analysis tools for understanding your room's acoustics

Spectrum Analyzer

Real-time FFT display with bars, filled, or line modes. Peak hold, RMS level, and crest factor.

Waterfall Display

3D time-frequency spectrogram showing sound decay with thermal, spectral, and grayscale schemes.

Phase Response

Phase angle visualization (-180° to +180°) and group delay for timing analysis.

Impulse Response

Time-domain waveform, RT60 decay visualization, and reflection identification.

Target Curves

Choose your desired frequency response or create a custom curve
