Method And Apparatus For Reducing Noise Pumping Due To Noise Suppression And Echo Control Interaction
US Patent:
2012029, Nov 22, 2012
Filed:
Jan 6, 2012
Appl. No.:
13/345351
Inventors:
Andrew John MacDonald - San Francisco CA, US
Jan Skoglund - San Francisco CA, US
Björn Volcker - Bromma, SE
Jan Skoglund - San Francisco CA, US
Björn Volcker - Bromma, SE
International Classification:
H04B 3/20
US Classification:
381 66
Abstract:
An input signal is processed through noise suppression (NS) and echo control (EC) via a multipath model that reduces noise pumping effects while maintaining EC performance. A copy of a “noisy” input signal is sent to an EC component before the noisy signal is sent to a NS component, which processes the signal first, when there is a consistent noise level for estimation. The copy of the pre-processing noisy signal is sent to the EC component along with a “clean” or “noise-suppressed” signal output from the NS component. The EC component analyzes the noisy signal as if the EC was the first component in the signal chain to determine what actions to take. The EC component then applies these actions to the clean signal received from the NS component.

Clipping Protection In Fixed-Width Audio Mixing
US Patent:
8428277, Apr 23, 2013
Filed:
Oct 11, 2011
Appl. No.:
13/271139
Inventors:
Jan Skoglund - San Francisco CA, US
Andrew John MacDonald - San Francisco CA, US
Andrew John MacDonald - San Francisco CA, US
Assignee:
Google Inc. - Mountain View CA
International Classification:
H03G 3/00
US Classification:
381104, 361119, 700 94, 708208, 708209
Abstract:
A mixing system provides both clipping protection and signal level conservation while the system operates in the original width type. The mixing system includes a first input multiplier multiplying a first digital input signal by a first gain value to provide a first scaled signal, a second input multiplier multiplying a second digital input signal by the first gain value to provide a second scaled signal, a combiner combining the first scaled signal and the second scaled signal to provide a combined signal, a soft limiter soft limiting the combined signal by reducing some of the amplitudes of the combined signal to provide a soft limited signal, and an output multiplier multiplying the soft limited signal by a second gain value to provide a mixed output signal, wherein the first gain value is a value that is equal to an inverse value of the second gain value.
Method And Apparatus For Multi-Channel Audio Processing Using Single-Channel Components
US Patent:
8320577, Nov 27, 2012
Filed:
May 20, 2011

Assignee:

International Classification:
H03B 29/00, H04M 9/08, H04B 3/20
US Classification:
381 711, 381 712, 381 86, 37940601, 37940606
Abstract:
Processing multi-channel audio streams using one or more arrangements of single-channel components. Components that only process the near-end, or capture stream, such as noise suppression (NS) components, are limited in how they can be suitably arranged for processing multi-channel streams. However, components that process the near-end stream using one or more inputs from the far-end, or render stream, such as acoustic echo cancellation (AEC) and automatic gain control (AGC) components, are arranged in one or more of the ways suitable for use with multiple channels.
