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.
Claims30
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, metadata associated with the audio device that influences the reproduction of the digital audio content, wherein the metadata includes 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;
- configuring at least one digital filter based on the received metadata;
- 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.
4 more elements
An audio device comprising:
- a receiver configured to
- receiving digital audio content that contains at least one audio channel signal;
- transmitting information identifying the audio device to a server;
- receiving, from the server, metadata associated with the audio device that influences the reproduction of the digital audio content, wherein the metadata includes 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;
- a processor configured to configure at least one digital filter based on the received metadata, 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;
- and
- 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.
4 more elements
A method for audio virtualization comprising:
- receiving, at a server, results of a user's hearing test;
- receiving information about at least one playback device associated with the user and at least one accessory device coupled to the playback device;
- storing the received test results and information in a virtualization profile associated with the user, the virtualization profile comprising a plurality of parameters for a room measurement profile based on acoustic measurements of a predetermined room, a listener hearing profile based on a spectral response curve of the user's hearing ability, a playback device profile based on a frequency response parameter of the playback device, and an accessory device profile based on a frequency response parameter of the accessory device;
- receiving request for a virtualization profile from a playback device associated with a user;
- and
- transmitting the requested virtualization profile to the playback device.
