Measuring Center vs Audio Spectrum Analyzer Pro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Measuring Center
This application allows users to perform spectral analysis of sound using their mobile devices. It supports various measurement functions and can connect to both wired and wireless external devices, or use the device's built-in microphone.
- 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

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

Verdict
The clearest difference is rating: Audio Spectrum Analyzer Pro at 4.4 against Measuring Center's 1.0. Audio Spectrum Analyzer Pro also leads on review sentiment (57% vs 19%) and ratings volume (239 vs 2). Measuring Center's advantage is in-app purchases (none vs 2) and update cadence (every 2 months vs every 7 months). On price, ads and device support there is nothing between them.

Both are free to download. Audio Spectrum Analyzer Pro sells 2 in-app purchases, starting at $19.99 per year. Measuring Center asks for nothing beyond the download.
Audio Spectrum Analyzer Pro holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Audio Spectrum Analyzer Pro has 239 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 19% of Measuring Center's written reviews are positive against 57% of Audio Spectrum Analyzer Pro's.
Measuring Center ships an update every 2 months, Audio Spectrum Analyzer Pro every 7 months. Both last shipped on November 2, 2026.
