Abstract
A device renders enhanced audio based on properties of an audio rendering system. For example, audio rendering system information of an audio rendering system associated with the device is used to determine an audio enhancement optimized for the audio rendering system. The OS of the device (e.g., a mobile phone) is queried to determine the audio rendering system information. The audio rendering system information is used to determine an audio enhancement, such as by querying a database storing associations between rendering system information and audio enhancements. The audio enhancement may include, for example, one or more types of audio processing (e.g., subband spatial processing, crosstalk processing, etc.) and particular parameters for the audio processing. The audio enhancement is applied to an audio signal to generate an enhanced audio signal that is provided to the audio rendering system.
