SPL Meter Lite!

This is the free ad-supported and limited-feature version of SPL Meter, which is our professional-grade sound level meter, also known as a decibel or dB meter, for your iPhone, iPad or iPod touch. Modeled after a traditional analog SPL meter, we have faithfully reproduced all the characteristics and qualities found in those meters, including the ballistics, ranges, filters, and decay rates. Also, if you are looking for more great acoustical and audio test apps, have a look at AudioTools, our premier app for audio professionals.
