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.

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
Flat
Zero deviation across all frequencies. Reference standard for mixing and mastering.
Harman In-Room
Research-based preference curve for natural, enjoyable sound in rooms.
House Curve A
Cinema-style curve with enhanced bass and smooth treble.
House Curve B
Balanced curve for music with subtle warmth.
