    Works fine on Samsung Galaxy S. Does anybody know the frequency range this program is measuring in when I don't apply any digital filter?

    As described, uses minimal permissions and runs in the background. Handy alarm for when sound reaches a certain dB.

    Fantastic and useful features, had to reinstall once after installing smart launcher but works perfectly now AND no annoying ads. The best by far.

    Great Sound (and light) meter App. No Ads and free! ... Just buy the author some coffee from within the app if you like. Also comes with high and low pass filters and sample rate adjustment and triggered alarms based on sound volume.
