Abstract: Context-aware loudness control of audio content may include choosing from a plurality of loudness level models based on an audio reproduction device, measuring loudness level of the audio content based on the chosen loudness model, processing the real-time loudness measurement of the input audio signal to output real-time loudness level adjustment, processing a momentary loudness measurement of the input audio signal to output a momentary loudness level adjustment, processing a short-term loudness measurement of the input audio signal to output a short-term loudness level adjustment, adjusting the input audio signal based on the real-time, momentary, and short-term loudness level adjustments to output a post-processing input signal, measuring long-term loudness of the post-processing input signal to output a long-term loudness measurement, processing the long-term loudness measurement to output a post-processing level adjustment, and processing the real-time, momentary, short-term, and post-processing level adjustments to output an overall loudness level adjustment.
