RevMeter Pro vs Impulso Pro

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.

Impulso Pro is a room acoustics measurement and analysis software. It allows you to measure the acoustic response of your room using your iPhone. You can visualize the measured reverberation time (RT) in octave bands and then simulate how the acoustic response of your room will be improved when adding artnovion acoustic products. You can enter room dimensions and select the type of room you are designing for. The app will then offer guidelines for the expected RT and you can select products to optimize the response accordingly. Impulso Pro also provides detailed plots of energy time curves, to check for undesirable reflections, a frequency plot, which you can zoom in and a table with the acoustic parameters of your measurements such as C80, D50, STI and Bass Ratio. Impulso Pro allows you to take a measurement with an internally generated signal if you are able to play it via a loudspeaker system, or using an external impulse source, such as a balloon, if you don’t. You can also display a spectral plot of the microphone input in real time. Compatible with built-in or external microphones.
