POST-PROCESSED REFERENCE PATH FOR ACOUSTIC ECHO CANCELLATION
First Claim
Patent Images
1. A system comprising:
- a speaker;
an acoustic echo canceller;
a post-processor configured to create a post-processed render signal associated with an audio input; and
a reference path operatively connected to the speaker, the post-processor, and the acoustic echo canceller, wherein the reference path provides the acoustic echo canceller with access to the post-processed render signal.

Abstract
A system includes a speaker, an acoustic echo canceller, a post-processor configured to create a post-processed render signal associated with an audio input, and a reference path operatively connected to the speaker, the post-processor, and the acoustic echo canceller. The reference path provides the acoustic echo canceller with access to the post-processed render signal.

9. A method comprising:
-
receiving a pre-processed render signal based on an audio input from a remote system; processing, by a post-processor, the pre-processed render signal to create a post-processed render signal; exposing, via a reference path coupled to the post-processor, the post-processed render signal to an acoustic echo canceller; and using the post-processed render signal, removing an echo via the acoustic echo canceller. - View Dependent Claims (10, 11, 12, 13)

14. A system comprising:
-
a speaker; an acoustic echo canceller; a post-processor configured to create a post-processed render signal associated with an audio input from a remote device; and a reference device operatively configured between the speaker, the post-processor, and the acoustic echo canceller, the reference device configured to expose the post-processed render signal to the acoustic echo canceller via a device driver. - View Dependent Claims (15, 16, 17, 18, 19, 20)
