RevMeter Pro vs Vibration Measurement

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.

Vibration Measurement is device sensor log tool that enables you to monitor the vibration from your iOS Devices. You are able to preview the vibration data with graphs. Perfect for the casual user with user friendly UI. Features: ∙ Show device acceleration data in X, Y and Z direction. • Show device acceleration data by color. [X - Red, Y - Green, Z - Blue] • Can easily determine vibration direction. • Preview live acceleration data in a graph. • Lightweight app with a small size, optimized for everyday use. Display Data: • Device acceleration in [G] gravity • Maximum Amplitude in [mm] millimetre for each X,Y and Z axis • Average [G] data • Maximum [G] data • Maximum Amplitude in [mm] millimetre • Device Acceleration Data retrieve every 0.1 second [10Hz] • Time and Date show as a reference Formula: v = at Device velocity [v] = device acceleration [a] * time [t] s = vt Displacement/distance [s] = Device velocity [v] * time [t] 1 g-units = 9.8066 Metres per second squared Quick Start Guide: 1. Place your device on top of any surface. 2. Tap reset to start measuring the vibration. 3. You can enable screen recording to record the vibration process. Usage: • Measure the vibration of machine, motor or anything else. • Measure vibration in car/truck while driving/idling. • Record the vibration while riding/driving on difference road condition. • And many more depend on your imagination. Tips: • Place your device with its screen facing up for stability during vibration measurement. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
