RevMeter Pro vs AcousticApp

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.

AkustikApp by objectiv is a precise sound measurement app for iOS, developed in Germany. It supports sound, noise and room acoustics measurement, evaluation and documentation. The app provides a professional measurement tool with RTA display for sound and noise measurement. Measurement values can be saved as screenshots and used for documentation. This makes AkustikApp suitable for capturing acoustic situations in offices, daycare centers, schools, meeting rooms, public spaces and private rooms. The app can also be used for orientation and documentation of environmental noise, such as traffic or aircraft noise. The integrated acoustic measurement uses the device microphone to display relative level values and acoustic characteristics. In addition, the app provides information about acoustic products and solutions, including acoustic pictures, ceiling absorbers, wall absorbers and other products for improving room acoustics.
