Abstract
An audio system and method for eliminating audio feedback including a first audio input arranged to receive a first audio signal, a first audio output arranged within a first predefined zone, the first audio output arranged to receive the first audio signal, a second audio output arranged within the first predefined zone, the second audio output arranged to receive the first audio signal, and one or more processors connected to a virtual matrix including a plurality of virtual channels connecting the first audio input, the first audio output, and the second audio output, and the one or more processors arranged to receive the first audio signal and attenuate or eliminate the first audio signal to the first audio output or the second audio output if an audio feedback is detected.
Claims20
An audio system for eliminating audio feedback comprising:
- a first audio input arranged to receive a first audio signal;
- a first audio output arranged within a first predefined zone, the first audio output arranged to receive the first audio signal;
- a second audio output arranged within the first predefined zone, the second audio output arranged to receive the first audio signal;
- one or more processors connected to a virtual matrix including a plurality of virtual channels connecting the first audio input, the first audio output, and the second audio output, and the one or more processors arranged to receive the first audio signal and attenuate or eliminate the first audio signal to the first audio output or the second audio output if an audio feedback is detected by the one or more processors.
An audio system for eliminating audio feedback comprising:
- a first audio input arranged to receive a first audio signal;
- a first audio output arranged within a first predefined zone, the first audio output arranged to receive the first audio signal;
- a second audio output arranged within the first predefined zone, the second audio output arranged to receive the first audio signal;
- one or more processors connecting the first audio input, the first audio output, and the second audio output, with one or more virtual channels of a plurality of virtual channels, the one or more processors arranged to receive the first audio signal and attenuate the first audio signal to the first audio output or the second audio output if an audio feedback is detected.
A method of eliminating audio feedback in an audio system comprising:
- receiving a first audio signal from a first audio input of the audio system;
- providing the first audio signal from the first audio input to a first audio output and a second audio output via one or more processors, the one or more processors including a first virtual input channel connected to the first audio input, a first virtual output channel connected to the first audio output, and a second virtual output channel connected to the second audio output;
- detecting, using audio feedback detection, an audio feedback between a first audio input and a first audio output or between the first audio input and a second audio output;
- attenuating or eliminating, via the one or more processors, the first audio signal to the first audio output;
- applying a gain, via the one or more processors, to the first audio signal or the second audio output.
