Filed:

Aug 20, 2003

Appl. No.:

10/644670

Inventors:

Thomas M. Drewes - Atlanta GA, US
James S. Joiner - Avondale Estates GA, US
Michael A. Pocino - Marietta GA, US
Craig H. Richardson - Marietta GA, US

Assignee:

Polycom, Inc. - Pleasanton CA

International Classification:

G06F 3/00

US Classification:

715727, 715763, 715967

Abstract:

A computer program of the type commonly known as a “wizard” is disclosed that initializes user interface software for controlling an audio conferencing device. The wizard allows the desired audio inputs (e. g. , microphone, telephones, etc. ) and audio outputs (speakers, recording devices, etc. ) to be chosen by an audio system administrator. Thereafter, the wizard allows an audio conferencing device (or devices) to be chosen by the administrator, or allows such a device(s) to be optimally chosen dependent upon the chosen inputs and outputs. The wizard then maps the inputs and outputs to the input and output ports on the audio conferencing device, a step which again can be performed manually by the administrator or automatically by the wizard. After reviewing the mapping results, the administrator finishes the wizard, which computes the mapping parameters and other audio-optimizing parameters for the selected inputs and outputs. These parameters are then loaded into the user interface software, which saves the administrator the time and inconvenience of having to set up and optimize these parameters from scratch.

US Classification:

Abstract:

A method and apparatus for detecting a singing frequency in a signal processing system using two neural-networks is disclosed. The first one (a hit neural network) monitors the maximum spectral peak FFT bin as it changes with time. The second one (change neural network) monitors the monotonic increasing behavior. The inputs to the neural-networks are the maximum spectral magnitude bin and its rate of change in time. The output is an indication whether howling is likely to occur and the corresponding singing frequency. Once the singing frequency is identified, it can be suppressed using any one of many available techniques such as notch filters. Several improvements of the base method or apparatus are also disclosed, where additional neural networks are used to detect more than one singing frequency.

Assignee:

Polycom, Inc. - San Jose CA

International Classification:

H04B 1/00

US Classification:

381119, 381109, 369 3, 369 4, 700 94

Abstract:

A distributed audio signal processing system having a plurality of linked audio signal processing units is disclosed. Each audio signal processing unit has physical channels for receiving and sending local audio signals and a high bandwidth interface for exchanging audio signals with other linked audio signal processing units. Each of the physical channels of each of the audio signal processing units is mapped to a corresponding global channel. Global channels can be combined to form virtual channels that can be processed as a signal channel. Combinations of virtual channels can be grouped into logical channel groups that can be controlled as a group.

Abstract:

Each audio signal processing unit has physical channels for receiving and sending local audio signals and a high bandwidth interface for exchanging audio signals with other linked audio signal processing units. Each of the physical channels of each of the audio signal processing units are mapped to a corresponding global channel. The audio signal processing system provides a tightly integrated, distributed signal processing matrix where any input signal or physical channel on any one of the signal processing units can be exchanged with any other of the linked audio signal processing units, thereby providing maximum flexibility for selecting signals to mix and determining how to process the signals.
