Abstract:
1. A radio configured to dynamically control cancellation of undesired signals in an audio stream, comprising: a noise cancellation processor configured to alter information in an audio stream by filtering out undesired signals in the audio stream; and a receiving component including at least one microphone configured to provide audio signals to the noise cancellation processor, the receiving component also configured to receive a data packet from a remote device including noise cancellation configuration information selected by a user of the remote device, to retrieve the noise cancellation configuration information from the data packet, and to dynamically apply the noise cancellation configuration information, while the radio is being used by a user, to noise cancellation settings associated with the noise cancellation processor to enable, disable or otherwise configure the noise cancellation settings such that the selection by the remote user can switch between listening to altered or unaltered audio streams from the radio, wherein when dynamically enabled by the remote user of the remote device, the noise cancellation processor is configured to suppress undesired signals associated with a subsequent incoming audio stream and to transmit the altered audio stream to the remote device, and wherein when dynamically disabled by the remote user of the remote device, the noise cancellation processor is configured to pass a subsequent incoming audio stream unaltered and to transmit the unaltered audio stream to the remote device, and wherein when dynamically enabled by the remote user of the remote device, the noise cancellation processor is configured to modify undesired signals associated with a subsequent incoming audio stream and to transmit a modified audio stream to the remote device.
