分贝计

_▒▓ ♪♬ Sound Meter ♬♩▓▒_ ▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔ Professional sound level meter for your device. It measures loudness or sound pressure (SPL) in decibels. Features: ─────── ■ direct reading in dB ■ 0 to 120dB+ (decibels) range ■ fast meter response ■ max/min values display ■ selectable falloff speed ■ 5% max error (device dependent) ■ A and C weighting method ■ mic range (headroom) extension ■ device's AGC disable option ■ time weighted average (TWA) display ■ predefined and custom calibration ■ vibrating alert on defined value ■ source: microphone or music played ■ classic vintage analog look ■ meter rotation ■ 2 meter faces ■ 18 case skins ■ tablet support ■ free Notes: ▔▔▔▔▔ 1. Due to microphone limitations on different devices the meter range is different, usually the low end of the scale cannot be achieved because of the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels. 2. Devices employing AGC (Automatic Gain Control) that cannot be automatically disabled by this app will have significant measurement errors and limited range. This is not app's fault. 3. If you have measuring problems or doesn't work at all, try to disable "Use high sampling rate" in settings, restart the device and recalibrate. 4.
