dB-Meter is a app for measuring the sound pressure in decibels (dB), in a cool "retro-style-design".
The upper analog display represents the average dB-level at 44.1 kHz, the lower the "peak level" at the same frequency.
The values are calculated in real time and can be read directly.
In addition, located within the analog displays a small box in which the level can be read as a digital value.
