In modern world tablet PCs or smartphones are playing greater role in our lives. Devices, comparable in power with personal computers, gained a big part of the consumer market, supplanting PCs. For general consumer mobile devices completely replaced the functionality of PC, but specific tasks are still mostly solved using computers. It mostly happens because of the lack of necessary software. Our company goes with the times and offers its customers the possibility of using mobile devices for sound measuring and analysing. We have developed an application for spectral analysis of sound for iOS. The application Measuring Center is simplified version of the program for PC, but it still has its reach functionality. The interface of the program is intuitive and easy to use. It supports both the wired Spl-Lab devices (USB BASS Meter, USB RTA Meter, etc.) and wireless devices, such Next-LCD(WiFi) or Next-USB(WiFi). Also you can make measurements using build-it microphone of your phone or tablet! Functions: Build-it mic support for AFC measurements Measuring the amplitude-frequency characteristic (AFC) of a signal - displaying the spectrum Displaying the signal waveform Measuring the Total harmonic distortion (THD) Measuring the sound pressure level (SPL, dB Drag, IdBL, ESPL, AMT, etc) Linear, logarithmic and octave view of spectrum Measuring the amplitude and frequency of the peak values of the spectrum Measuring average level of sound pressure in time (Bassrace, Bass Boxing, AMT SPL-Show, etc) Measuring the average in time and whole spectrum sound pressure level (SQL) Supports the wired and wireless Spl-Lab devices ## Key features - Spectral sound analysis - Amplitude-frequency characteristic (AFC) display - Signal waveform display - Total harmonic distortion (THD) measurement - Sound pressure level (SPL) measurement - Support for wired and wireless Spl-Lab devices - Built-in microphone support ## Recent user reviews (10 of 27) All indexed reviews: https://appshunter.io/ios/app/measuring-center/id1052916114/reviews.md ### 1/5 — App Crashes RTA Mode *2026-03-12, version 1.45* The only option available with then native microphone on iPad is the RTA. However, when you go to measure or press play the entire app crashes. The camera feature does work and you can change the cameras. That function is very attractive. I wonder if this will work better when connected to a sensor. - For now, it’s not working. I hope that it gets addressed and as soon as it does I will update my rating! @PhiMobileSounds ### 1/5 — Не работает на iPhone *2025-11-03, version 1.45* Не работает на iPhone ### 3/5 — Don't waste your time *2025-06-30, version 1.43* The app is extremely finicky when connecting it to your bass meter. I have only ever had luck consistently connecting my bass meter through a wired connection to my windows laptop. 1. Turn on the bass meter 2. Plug it into your computer 3. Open the spl lab application on your computer 4. Select "next lab" in the options That's how it will work every time. Don't bother downloading the app for IOS. ### 1/5 — В чем проблема ? *2025-03-16, version 1.43* Не работает на айфоне ### 2/5 — Stürzt ab ! *2024-12-25, version 1.40* Stürzt beim Speichern vom Video immer wieder ab. Nutze ein iPhone 15. ### 5/5 — Spl lab wireless bass meter (third edition) *2024-01-16, version 1.33* IPhone 12, работает, как на iOS 16 так же и работает после обновления на iOS 17, кто говорит, что не работает - ребят, читайте инструкцию по настройке приложения ! И да, пока не подключитесь к датчику - приложение будет вылетать, после того, как подключитесь ничего вылетать не будет ! В общем у меня всё прекрасно работает, спасибо разработчикам.👌🏻 ### 1/5 — iPhone 11 *2023-08-18, version 1.32* Не работает приложение, при попытке замера сразу вылетает. iOS 16.6 ### 2/5 — iPhone Probleme *2023-06-13, version 1.32* Ich kann mein SPL LAB Wireless nicht mit dem iPhone verbinden. Ich bin mit dem Handy im SPL Lab WLAN aber die App stürzt jedesmal ab. Manchmal geht es aber sehr oft nicht. Wenn die App funktioniert ist alles super ### 1/5 — Не работает *2023-05-17, version 1.32* Устройство iphone xr ### 1/5 — Не работает *2023-01-23, version 1.32* Не работает ## Frequently asked questions about Measuring Center ### What is Measuring Center used for?
