Techniques and apparatus for audio isolation in video processing

摘要

An apparatus may include a digital display, processor circuit, and an audio isolation component. The audio isolation component may be operative on the processor circuit to identify a selected position on the digital display during presentation of a video, where the video comprises a video stream and two or more audio streams. The audio isolation component may be operative on the processor circuit to generate an audio beam from the one or more audio streams based upon the selected position.

主权项

1. An apparatus, comprising:
a digital display; a processor circuit; and an audio isolation component operative on the processor circuit to:
identify a selected position on the digital display during presentation of a video on the digital display, the video comprising a video stream and multiple audio streams, the multiple audio streams comprising audio recorded by an array of microphones prior to the presentation;determine, based on the selected position, an angular displacement relative to a lens of a camera used to record the video; andgenerate an audio beam centered at the angular displacement from at least one of the multiple audio streams based upon the selected position.
