Measuring Center

Spl-Lab

About this app

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 Android. The application Measuring Center for Android 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 as Wireless Bass Meter. Also you can make measurements using build-it microphone of your phone or tablet!

Ratings and reviews

I bought the full version. Works great on S9 / android 10, with the spl-lab wireless bass meter third edition. You can either use this app with wifi, or with the included OTG usb-c cable. Follow web instructions. The video score overlays are really cool, but if you're streaming bluetooth audio while recording a video on the same device with this app, it wont record the audio portion. Just stream off of another device or use usb on your deck, if you want the whole video/score overlay with sound.

I bought into the spl lab meter on pre order when they first came out. Within 0.1 db of my termlab and app has worked on a dozen Android devices for me over the years. Far more convenient than having to set up TL especially at shows. My big gripe is that it should keep phone or tablet from turning off the screen while using it.

The app has a clean and easy to use UI, but there are quicker reacting more responsive apps available. I found the app isn't really optimised for internal microphones when used to determine car audio levels. The app also demands access to specific location information on every startup, even if location permissions are denied. It may suit another user, but it's not for me.
