Title:
AN INTEGRATED AMBIENT AUDIO TRANSFORMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/039657
Kind Code:
A3
Abstract:
A method and device for transforming ambient audio are provided. Example embodiments may include monitoring ambient audio proximate to a sound processing device located in an environment. The device may access memory to obtain transformation audio and generate output transformation audio based on the transformation audio and the ambient audio to provide modified output audio for propagation into the environment. The device may at least reduce feedback of the modified output audio received by the sound processing device from the environment.
