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. |

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. |
