RT60
Professional acoustic measurement tool that analyzes reverberation decay time across seven octave bands. Designed for audio engineers, acousticians, and home theater enthusiasts.
Precision Decay Analysis
Accurately measure reverberation decay time using the interrupted noise method. ISO 3382 compliant T20 and T30 calculations give you laboratory-grade results from your mobile device.
Seven Octave Bands
Get detailed frequency-specific reverberation data from 63Hz to 4kHz. Each band displays current SPL, peak level, noise floor, RT60 value, and headroom indicator.
Built-In Pink Noise
The integrated pink noise generator outputs a spectrally balanced test signal with equal energy per octave. Ideal for acoustic measurements and room analysis.
Flexible Microphone Options
Choose between internal mode with frequency compensation for built-in mics, or external mode with flat response for calibrated measurement microphones.
Professional Documentation
Export measurements as PDF reports or CSV spreadsheets for documentation, client reports, or further analysis. Share results directly from the app.
Project-Based Workflow
Save each measurement session with location name, notes, date, method used, microphone type, and both overall and per-band RT60 values.
Seven Octave Band Analysis
ISO 3382 Compliant Methods
T20 Method
Measures decay from -5dB to -25dB below peak level. Suitable for most treated rooms and studios with moderate background noise.
T30 Method
Measures decay from -5dB to -35dB below peak level. Provides greater accuracy in quiet environments with low noise floor.
Who Uses RT60
Recording Studios
Verify acoustic treatment effectiveness and optimize room response. Ensure your mix environment meets professional standards for accurate monitoring.
Home Theater
Calibrate your listening space for optimal dialogue clarity and immersive surround sound. Identify and address problematic room modes.
Live Sound Venues
Assess venue acoustics before events. Understand room characteristics to optimize PA placement and processing settings.
Architectural Acoustics
Document room acoustic parameters for new construction and renovation projects. Verify design specifications are met.
Educational Spaces
Evaluate classroom and lecture hall acoustics for speech intelligibility. Ensure learning environments meet acoustic standards.
Worship Spaces
Balance reverberation for both spoken word clarity and musical richness in churches, synagogues, and mosques.
