Great (& free!) measuring tool. Thanks.
Most accurate meter I've ever seen! Every other dB meter app I've ever tried has been off by a significant factor, making it pretty much useless. But after comparing to known values, this one is accurate down to about 2 dBA! Great UI, awesome advanced features for people who know what they're doing.
Does measure but with significant delay The audio signal cut-off point is displayed with an average of 250ms delay off real-time metering. Smart tools Db meter has a much faster response and sampling rate. However this app is good for free and ad free product too.
Absolute crap. Cannot calibrate on Moto Droid Turbo 2. I'm an audio tech with access to accurate reference equipment, and this app isn't even close. Setting the cal at 1kHz at one range should work for all ranges, but it doesn't. Also, touch screen controls are very inconsistent and unreliable. Changing ranges is a supreme pain in the a$$.
Looks pretty, but poor at measuring SPL Nice looking, a lot of options, but the readings for many sounds, including single freq tones, are not even close. It is not a calibration issue, this is a design issue. This design does not respond to a single freg tone anything like an IEC651 SPL meter.
