SYSTEM AND METHODS FOR PROCESSING STEREO AUDIO CONTENT

摘要

A system can include a hardware processor that can receive left and right audio signals and process the left and right audio signals to generate three or more processed audio signals. The three or more processed audio signals can include a left audio signal, a right audio signal, and a center audio signal. The processor can also filter each of the left and right audio signals with one or more first virtualization filters to produce filtered left and right signals. The processor can also filter a portion of the center audio signal with a second virtualization filter to produce a filtered center signal. Further, the processor can combine the filtered left signal, filtered right signal, and filtered center signal to produce left and right output signals and output the filtered left and right output signals.

主权项

1. A method comprising:
under control of a hardware processor:
receiving left and right audio channels;combining at least a portion of the left audio channel with at least a portion of the right audio channel to produce a center channel;deriving left and right audio signals at least in part from the center channel;applying a first virtualization filter comprising a first head-related transfer function to the left audio signal to produce a virtualized left channel;applying a second virtualization filter comprising a second head-related transfer function to the right audio signal to produce a virtualized right channel;applying a third virtualization filter comprising a third head-related transfer function to a portion of the center channel to produce a phantom center channel;mixing the phantom center channel with the virtualized left and right channels to produce left and right output signals; andoutputting the left and right output signals to headphone speakers for playback over the headphone speakers.
