摘要： The overall performance of an ANC system may be improved by configuring the ANC system to perform adaption in the frequency domain. The ANC systems may be configured to update an algorithm of an adaptive filter based, at least in part, on the first input signal, the second input signal, and a feedback signal that is based on an output of the adaptive filter. Updating may include changing parameters of the algorithm based on a SDR based, at least in part, on the first input signal. Updating may also include normalizing a step size and processing at least full band information for the input signal in a frequency domain to generate coefficient values for the algorithm. Updating may also include applying a frequency domain magnitude constraint on adaptive filter coefficients.

摘要： A method for providing a diversity ring tone to a called party terminal (30) under the control of a calling party terminal (10), comprises the steps of: initiating a call from the calling party terminal (10) to the called party terminal (30); determining whether the called party terminal (30) is available to receive a call; if so, retrieving and playing a ring tone stored at the calling party terminal (10); and establishing connectivity between the calling and called party terminals (10, 30), and turning on a speaker of the called party terminal (30), thereby making the ring tone, which is being played at the calling party terminal (10), audible by means of the speaker. Alternatively, the determination step further comprises making the called party terminal (30) ring in a manner in accordance with the called party's configuration, in the case that the called party terminal (30) is available to receive a call; the step of retrieving and playing a ring tone further comprises: prior to performing playing, delaying for a predefined period of time; and the step of establishing connectivity and turning on a speaker further comprises, at the same time as turning on the speaker, stopping ringing in the manner in accordance with the called party's configuration. A system for providing a diversity ring tone is also described.

摘要： The handling of disturbances to audio signals may be improved with an adaptive noise cancellation (ANC) system that performs frequency-domain adaption. The ANC systems may be configured to determine if a disturbance is present at a first frequency in the second input signal received from the reference microphone. The ANC systems may update an algorithm of an adaptive filter based, at least in part, on the first input signal, the second input signal, and a feedback signal that is based on an output of the adaptive filter by changing parameters of the algorithm such that the adaptive filter adapts around the first frequency differently than other frequencies when the disturbance is present.

摘要： A controller for an adaptive noise canceling (ANC) system simplifies the design of a stable control response by making the ANC gain of the system independent of a secondary path extending from a transducer of the ANC system to a sensor of the ANC system that measures the ambient noise. The controller includes a fixed filter having a predetermined fixed response, and a variable filter coupled together. The variable response filter compensates for variations of a transfer function of a secondary path that includes at least a path from a transducer of the ANC system to a sensor of the ANC system, so that the ANC gain is independent of the variations in the transfer function of the secondary path.
