Auralize
Read full descriptionHide full description
Auralize is an acoustic measurement tool for iPhone that combines sound level meter and decibel meter features to measure, record, and document sound levels in the field. Built by acoustic and computer engineers, Auralize uses a calibration correction factor obtained in a laboratory. Up to 4000 Hz, the app qualifies as a Class 2 measurement, delivering reliable accuracy for technical fieldwork. Track sound levels in dB(A) in real time, view the equivalent level (Leq), the maximum level, and sound pressure (SPL) data with acoustic weighting. During measurement, follow sound variations on a chart updated in real time. More than measuring, Auralize helps you keep the full context of every measurement organized — from the field record to the final report. REAL-TIME MEASUREMENT Track sound levels in dB(A), the equivalent level (Leq), the maximum level, and sound pressure (SPL) information throughout the measurement. MEASUREMENT CHART See in real time how the sound level varies over the measurement and clearly follow how the environment behaves. AUDIO RECORDING Save the measurement together with a WAV-format audio recording, keeping a sound record of the analyzed moment. MEASUREMENT WITH CAMERA Perform acoustic measurements with photo and video, combining visual context with sound recording and real-time acoustic, location, and time data. PHOTOS AND LOCATION Add photos and location information to measurements, including coordinates and city, to record the context of every analysis carried out in the field. PROJECT ORGANIZATION Group your measurements into projects and keep an organized history to review past records and results whenever you need. PDF REPORTS Gather the data recorded during measurement into PDF reports ready to review and share. FROM MEASUREMENT TO REPORT Sound levels, charts, recordings, photos, location, and results stay organized in a single flow, making acoustic measurement work simpler and more complete. Measure. Record. Organize. Share. Terms of Use and Privacy Policy By using Auralize, you agree to the app's Terms of Use and Privacy Policy. Auralize works locally: your measurements, recordings, photos, videos, and location data are stored on your own device and are not sent to our servers. Subscriptions are processed by Apple and managed by RevenueCat, and we collect anonymous usage data (via Mixpanel) only to improve the app. Auralize may show partner ads, with no ad tracking (IDFA).

"Reverb Time Analyzer" is an acoustic analysis tool for iPhone that allows you to measure the reverberation time of a room. Would you like to control sound reverberation in your listening room? Knowing the reverberation time is key to creating a comfortable sound space. For example, you can obtain objective data on various acoustic disturbances, such as high room reverberation, poor intelligibility, excessive flutter echo, and howling. The app can analyze the reverberation time using the interrupted noise method, in which a random test noise signal is generated from the iPhone's speaker and then turned off. Up to six consecutive measurements are possible, enabling reverberation time analysis and spectrogram analysis. Features: - Reverberation time analysis by interrupted noise method: RT30/RT20, RT60 converted from RT30/RT20. - Test source: White noise - Pre-measurement checks and settings (LVL): Measurement of background noise level and adjustment of test signal output level. - Sound pressure level measurement and result display (MSR): Up to 6 consecutive measurements. - Sound recording and playback function - Reverberation time analysis results display (RT): Reverberation decay curve, Reverberation time of each measurement, Sample average reverberation time (Avg) of valid measurement times. - Measurement error detection function. - Octave-band spectrogram (OCT): 1/3, 1/48 octave band. - Delay start time setting: 0 - 60 seconds - Capture function (Snap) Usage: The following steps are used to analyze reverberation time measurements. Step 1 must be performed for each environment. 1) Pre-measurement checks and settings (LVL): Select RT30/RT20 mode. Measure the noise level with "MUTE" and confirm that the appropriate background noise level for reverberation time analysis is less than about 50dB. Then, to ensure the dynamic range of the test sound source, play the output noise signal using "NOISE" and adjust the slider so that the sound pressure level of the observed sound exceeds the red line. If the sound pressure level is insufficient, adjust the iPhone audio volume. Also, if you need to change the RT30/RT20 mode, please start over from the first step. 2) Sound pressure level measurement and result display (MSR): Tap the start button to play a burst of a test sound source and perform sound pressure level measurement and reverberation time analysis. It can be discontinued with the stop button and will automatically stop after 6 consecutive measurements. (Start button is available only when "Avg" is selected.) 3) Reverberation time analysis results display (RT): Displays the reverberation time for each measurement, the average reverberation time (Avg) for valid measurement sessions, and the reverberation decay curve. 4) Octave-band spectrogram (OCT): Displays 1/3 or 1/48 octave band spectrogram analysis results of the observed sound at each measurement session. Notes: - RT60 is obtained by analyzing the time variation of the gain of the observed noise cutoff sound as it decays by 60dB. Since it is quite difficult to actually achieve a dynamic range of 60dB, a reverberation time RT30 with 30dB decay is measured and converted to RT60. Additionally, RT20 is used in cases where RT30's conditions cannot be met (such as when the background noise level is extremely high), but its measurement accuracy is lower than that of RT30. - The reverberation time may not be analyzed correctly if high levels of noise are present during the measurement of background noise or measurement test signals. - The sound level (dB) display is the value of the sound pressure level (Z-characteristics, without frequency weighting correction) received by the iPhone's built-in microphone. Due to its flat response, it generally measures at higher values than a standard sound level meter (dBA). Please visit our iOS app support page for more information on this app.

Verdict
The clearest difference is price: Auralize at Free against Reverb Time Analyzer's $6.99. Auralize also leads on update cadence (every 3 months vs every 8 months) and iOS requirement (16.2 vs 26.2). On ads, in-app purchases and device support there is nothing between them.
