Abstract
Devices and methods for digital sound leveling are disclosed. The subject devices and methods can be used to reduce the risk of noise induced hearing loss. According to an embodiment, an audio file can be parsed into frames that are filtered using an A-weighted digital filter and scaled to a desired power level. Accordingly, the dynamic range of an audio output at a particular volume level can be controlled.
