About AudioMeter
AudioMeter is an Android VU-style meter for displaying audio levels. Users can choose among several calculation methods, including dBFS, RMS, logarithmic RMS, square-root RMS, maximum level, and average level. These methods respond differently to quiet signals and noise, so the app provides alternatives for different measurement conditions. RMS, or root mean square, represents an average signal level, while dBFS expresses level relative to digital full scale. Maximum mode follows the loudest part of a sample, and simple average mode uses the average value. The app’s description notes that some approaches can be less sensitive at low volume or more responsive to background noise. AudioMeter is intended for viewing an audio level with a formula suited to the environment and input. It focuses on displaying level measurements rather than recording or editing sound.
