SPL and Spectrum Analyser

About this app

SPLMeter shows SPL (deciBels) of the Android's mic signals, and their frequency spectrum. The meter has three speeds: Fast, Medium and Slow. Shows peak envelope and frequency of maximum intensity, and clipping. ISO 1/3 Octave bars and Spectrogram.

(If you need a more fully featured RTA, with 1/1, 1/3 and 1/6 octave display, RT60, Noise Criteria, A&C Weighting etc. combined with a signal generator, please take a look at my "AudioTool" app in Android Market.)

Ratings and reviews

I've had this app for quite a while...worked great until recently the decibel readings suddenly jump up about 10db after a short period of use. I don't usually pay attention to the number, but my graph readings shoot off the charts as well, so it really hinders the usefulness of the app.

Really good , and app can be moved to external SD memory

The font needs to be larger on the frequency of numbers.
