By Curtis Emery
For the best results, or should I say the most accurate results, you need to be using a professional USB mic to take audio measurements with your mobile device. Once you have gone though the apps to see which one has the features you like, check out my article: Must Have Pro USB Attachments for Precise Audio Measurement With Android and iOS Apps, to explore your options for the best mobile ready mics.
If you’re an AV professional on the go the last thing you need is more tools—it is important to get to a job, get it done and move on to your next project without being weighed down. As mobile apps become more comprehensive, the AV professional is beginning to leave their expensive equipment at home, wielding only their smart device when they walk on-site.
SPL meters can be expensive, and depending on where you buy them, unreliable. Here is a collection of dB-SPL meter mobile apps that can do a lot more than just read sound pressure levels. The following apps can not only measure SPL, some of them can graph real time audio, others can save data for comparison (think synchronizing speakers or just to jog your memory) and the list of customizable features and settings boils most physical dB-SPL meters down to one digital app at a fraction of the price. Whether you are taking room noise measurements, or just getting your home entertainment center to sound perfect, this list of mobile apps will be just what your Android or Apple smart device needs.
