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.

ORBIS Multi-Process Viewer (OMPV) Note: This application can only be fully utilized in combination with our ORBIS Multi-Process Suite (OMPS). ORBIS MPS is the enabler for Industry 4.0 processes with SAP ERP. Processes are networked, dialogized and visualized on this platform in “real-time”. Description: Process information from the SAP processes, machines and systems can be visualized anywhere and at any time on any terminal device thanks to ORBIS MPS. With our app, you can easily visualize “real-time information” from the SAP ERP system on mobile terminal devices that use the iOS operating system. The SAP system connection data and the mobile application to be used are entered in the app’s configuration. You can then easily log in with your SAP user data on the iOS device. Functions: • Displaying ORBIS MPS applications. • Creating, editing and deleting profiles for SAP systems. • Potentially using the profile editor to manually create or edit profiles (in the role of administrator only). • Creating new profiles by scanning a profile QR code; the administrator password is not needed to do this. • Displaying profile QR codes for copying profiles. • Defining default profiles: the default profile is started automatically once the application has been launched. • Accessing the camera from within SAP: scanning barcodes and taking pictures. Conditions: • Access to the camera for scanning codes and taking pictures. • Access to the internet to display ORBIS MPS applications. • Implementation of the ORBIS Multi-Process Suite solution.
