Abstract

This specification describes technologies relating to generating audio mixes for listening environments. A method is provided that includes receiving digital audio data; receiving an environmental input, the environmental input being associated with the listening environment; calculating one or more audio parameters for the digital audio data based on the received environmental input, the calculating including: calculating a particular intensity level for the digital audio data, and processing the digital audio data according to specified reference levels; and generating an audio mix for the digital audio data according to the calculated audio parameters.
