Abstract
A method includes receiving digital audio data at an audio adjustment system. The method includes converting a portion of the digital audio data to an analog audio signal with a digital-to-analog converter of the audio adjustment system to form a sample analog audio signal. The method includes determining a dynamic range of the sample analog audio signal with the audio adjustment system. The method also includes modifying a metadata parameter of the digital audio data with the audio adjustment system when the dynamic range of the sample analog audio signal is below a threshold. The metadata parameter is a dialog normalization parameter.
