First Claim
Patent Images
1. A method for use in an audio device, the method comprising:
- receiving, by the audio device, digital audio content that contains at least one audio channel signal;
transmitting information identifying the audio device to a server;
receiving, from the server, a device profile based on a frequency response parameter of a device;
accessing a room measurement profile based on acoustic measurements of a predetermined room;
accessing a listener hearing profile based on a spectral response curve of a user hearing ability;
configuring at least one digital filter based on said device profile, said room measurement profile and said listener hearing profile;
filtering the at least one audio channel with the corresponding at least one digital filter to produce a filtered audio signal; and
outputting the filtered audio signal to an accessory device coupled to the audio device to reproduce the digital audio content.

Abstract
A method and apparatus may be used to perform personalized audio virtualization. The apparatus may include a speaker, a headphone (over-the-ear, on-ear, or in-ear), a microphone, a computer, a mobile device, a home theater receiver, a television, a Blu-ray (BD) player, a compact disc (CD) player, a digital media player, or the like. The apparatus may be configured to receive an audio signal, scale the audio signal, and perform a convolution and reverberation on the scaled audio signal to produce a convolved audio signal. The apparatus may be configured to filter the convolved audio signal and process the filtered audio signal for output.

16. An audio device comprising:
-
an interface configured to receive digital audio content that contains at least one audio channel signal; transmit information identifying the audio device to a server; and receive from the server a device profile that influences the reproduction of the digital audio content; and a processor configured to access a room measurement profile based on acoustic measurements of a predetermined room and a listener hearing profile based on a spectral response curve of a user hearing ability; and configure at least one digital filter based on the device profile, room measurement profile, and listener hearing profile, wherein the processor is configured to filter the at least one audio channel signal with the corresponding at least one digital filter to produce a filtered audio signal; wherein the processor is configured to output the filtered audio signal to an accessory device coupled to the audio device to reproduce the digital audio content. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
