Independent claims
What is actually asserted, verbatim.
1. A method for enhancing an audio signal, comprising, by a circuitry of a device: transmitting a request to an operating system of the device for rendering system information of an audio rendering system associated with the device, the operating system operating the device and the audio rendering system; receiving, from the operating system of the device, the rendering system information, wherein the rendering system information comprises data representative of a communication path of the audio signal, wherein the data representative of the communication path of the audio signal includes metadata indicative of an audio consumption software application associated with the audio signal; querying a database using the data representative of the communication path of the audio signal; receiving, responsive to querying the database, an audio enhancement, wherein the audio enhancement is mapped, in the database, to the data representative of the communication path of the audio signal; applying the audio enhancement to the audio signal to generate an enhanced audio signal; and providing the enhanced audio signal to the audio rendering system.
10. A device, comprising: an audio rendering system; and circuitry configured to: transmit a request to an operating system of the device for rendering system information of an audio rendering system associated with the device, the operating system operating the device and the audio rendering system; receive, from the operating system of the device, the rendering system information, wherein the rendering system information comprises data representative of a communication path of the audio signal, wherein the data representative of the communication path of the audio signal includes metadata indicative of an audio consumption software application associated with the audio signal; query a database using the data representative of the communication path of the audio signal; receive, responsive to querying the database, an audio enhancement, wherein the audio enhancement is mapped, in the database, to the data representative of the communication path of the audio signal; apply the audio enhancement to the audio signal to generate an enhanced audio signal; and provide the enhanced audio signal to the audio rendering system.
19. A non-transitory computer readable medium storing instructions that when executed by one or more processors configure the one or more processors to: transmit a request to an operating system of a device for rendering system information of an audio rendering system associated with the device, the operating system operating the device and the audio rendering system; receive, from the operating system of the device, the rendering system information, wherein the rendering system information data representative of a communication path of the audio signal, wherein the data representative of the communication path of the audio signal includes metadata indicative of an audio consumption software application associated with the audio signal; querying a database using the data representative of the communication path of the audio signal; receiving, responsive to querying the database, an audio enhancement, wherein the audio enhancement is mapped, in the database, to the data representative of the communication path of the audio signal; apply the audio enhancement to the audio signal to generate an enhanced audio signal; and provide the enhanced audio signal to the audio rendering system.
43. A method for enhancing an audio signal, comprising, by a circuitry of a device: transmitting a request to an operating system of the device for rendering system information of an audio rendering system associated with the device, the operating system operating the device and the audio rendering system; receiving, from the operating system of the device, the rendering system information, wherein the rendering system information comprises data representative of a communication path of the audio signal, wherein the communication path of the audio signal is a headphone jack, built-in speakers of the device, a Bluetooth connection, a Wi-Fi connection, a universal serial bus (USB) connection, or a high-definition multi-media interface (HDMI); querying a database using the data representative of the communication path of the audio signal; receiving, responsive to querying the database, an audio enhancement, wherein the audio enhancement is mapped, in the database, to the data representative of the communication path of the audio signal; applying the audio enhancement to the audio signal to generate an enhanced audio signal; and providing the enhanced audio signal to the audio rendering system.

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.
