Core Features
- Import WAV impulse responses or use a complete sample

- Estimate EDT, T20, T30, C50, and C80 by band
- Map axial, tangential, and oblique room modes
- Compare listening positions and treatment scenarios
Private by Design
No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.
Use It Responsibly
Planning and education aid. Phone microphones, playback systems, background noise, placement, and calibration affect results; use calibrated measurement practice for design decisions.
