## What is RevMeter 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.

### 2/5 — Crashes iPhone 17 Pro

*2025-08-29*

Really awesome results when it works but not reliable enough to use unfortunately :(

### 1/5 — Drops out constantly

*2025-03-13, version 4.1*

Drops out constantly! Avoid this app

### 1/5 — Horribly buggy and no results view

*2024-09-03, version 4.1*

App continually crashes. The trigger threshold for an impulsive noise source is not adjustable. No details results are able to be viewed within the app - only a heavily smoothed version of the energy decay curve. Don’t bother - total waste of money.

### 1/5 — Keeps crashing

*2024-02-17*

Keeps crashing….

### 1/5 — Echt jetzt … das geht gar nicht!

*2023-02-14, version 4.1*

Die App stürzte bei fast jeden Start an. IMHO unbrauchbar. Hab das Bundle gekauft. Bitte Geld zurück!

### 1/5 — Nicht kaufen!

*2022-08-23, version 4.0*

Völlig unstabil, stürzt permanent ab oder lässt sich nicht öffnen, Audio Transport via SharePlay nicht machbar. Frech für so eine unausgereifte App Geld zu verlangen, Finger weg davon!!

### 2/5 — Stürzt leider sehr oft ab.

*2022-02-10, version 4.0*

Bevor ich zu einer Messung komme muss ich die App meist 5-6 mal starten.

### 2/5 — Keeps crashing

*2020-09-17*

I bought the app and it worked once. Now it keeps crashing even if I reset my phone and uninstall and reinstall the app.

### 5/5 — Easy feedback for your voiceover space!

*2020-08-16*

This app is helpful for testing the reverberation of different rooms as well as the impact of acoustic treatments.  Now I can do a before and after test as I hang blankets and other sound absorbing materials.

### 5/5 — Hilfreiche App(s)

*2015-08-16, version 3.6*

Ich habe das ganze Bundle von Mess- und Ton Generator Apps. Und habe damit meine Raumakustik gut nachvollziehen und verbessern können.
Bin natürlich kein Tontechniker. Aber wenn man bedenkt, dass man allein mit einem iPhone bewaffnet zu sehr aussagekräftigen Ergebnissen kommen kann: Hammer! Danke für die coolen Apps!
