RevMeter Pro: Professional Reverberation Time Analysis RevMeter Pro is a precision tool designed to measure the reverberation time (RT60) of any room directly from your iPhone. Whether you are an audio enthusiast, student, or acoustician, RevMeter Pro provides quick and reliable acoustic analysis using industry-standard calculation methods. Key Features: Dual Measurement Modes: Supports both Impulse (Burst) and Interrupted Noise methods for versatile testing. RT20 & RT30 Standards: Calculates RT60 based on RT20 and RT30 decay slopes, compensating for the dynamic range limitations of mobile hardware. Data Export: Easily share comprehensive measurement data (CSV) and visual charts (Screenshots) via email or save them to your device for further analysis. Visual Analysis: View real-time decay curves and spectrograms to understand room acoustics instantly. About Reverberation Time: Reverberation Time (RT60) is the time required for sound pressure to decay by 60 dB. Because achieving a full 60 dB dynamic range is challenging in many environments, RevMeter Pro utilizes the established RT20 and RT30 extrapolation methods to accurately compute the RT60 value. Measurement Methods: Impulse Method: Measures the room's response to a sudden sound, such as a hand clap or balloon burst. Interrupted Noise Method: Generates a controlled noise signal (Pink/White Noise) through external speakers and measures the decay once the source is cut off. Disclaimer: While RevMeter Pro has been calibrated against professional-grade equipment, it is intended for educational and reference purposes only. It should not replace certified hardware for critical professional certification. The author assumes no liability for damages resulting from the use of this software.

Measure the acoustics of a room... with a simple clap ClapReverb lets you instantly evaluate the reverberation time (RT) of an enclosed space — a key factor in determining a room’s acoustic quality. Is the room too echoey? Or too dry? Get the answer in just a few seconds. Simple, fast, and precise With a clean design and intuitive interface, all it takes is a quiet moment and five hand claps. Place your phone or tablet at the center of the room, wait for the signal, and clap your hands (slightly cupped palms). The app analyzes the relevant frequencies and provides a clear picture of the room's acoustics. A professional tool, accessible to everyone Whether you’re an architect, interior designer, engineer, teacher, musician — or simply curious — ClapReverb is for anyone who wants to integrate acoustics into their projects. Easily compare your results to typical reference values and decide if acoustic treatment is needed. Scientifically validated The app’s results have been verified through a rigorous experimental protocol, presented at the 26th International Congress on Sound & Vibration.
