The method comprises: playing a first segment of the signal; skipping to a second segment that is not contiguous with the first segment; and playing the second segment, wherein at least one of the first and second segment is played at a rate different from the rate at which it was recorded. | 2015-03-19 |
20150078563 | ACCOUSTIC WAVE REPRODUCTION SYSTEM - A method of and a system for generating an acoustic wave representing reverberations from a desired acoustic environment are described including having a recording surface ( | 2015-03-19 |
20150078564 | ECHO CANCELLATION ALGORITHM FOR LONG DELAYED ECHO - This document discloses one or more systems, apparatuses, methods, etc. for implementing an echo cancellation algorithm for long delayed echo that is created during a wire or wireless voice communications. In an implementation, a WiDi feature in a device during the wire or wireless voice communications may add an additional echo delay in addition to channel multipath delay when an audio sound signal travels from a WiDi component to a microphone of the device. In this implementation, a separate delay estimator is configured to estimate total delay. The estimated total delay is fed back to an adoptive filter component for long delay echo cancellation. | 2015-03-19 |
20150078565 | Dual-Diaphragm Microphone Module to Reduce Vibration Noise - A microphone module disposed in an electronic device for reducing echo noise. The microphone module includes a casing, a first diaphragm disposed in the casing, a second diaphragm disposed in the casing and a substrate disposed between the first diaphragm and the second diaphragm and joined to the casing to define a first space and a second space which are isolated and separated from each other. The first diaphragm is disposed in the first space, the second diaphragm is disposed in the second space, and the substrate is electrically connected with the first diaphragm and the second diaphragm. | 2015-03-19 |
20150078566 | Acoustic Echo Cancellation - A method and system for acoustic echo cancellation stores received far-end data in a first buffer. When the far-end data in the first buffer exceeds a predefined length, the stored far-end data is used to calculate echo estimate data. The echo estimate data is stored in a second buffer. Whenever microphone data is received the error data is calculated independent of echo estimate data availability. In particular, subsequent to sufficient echo estimate data being stored in the second buffer and responsive to the reception of the microphone data, the error data is calculated by subtracting, from the microphone data, corresponding echo estimate data stored in the second buffer. | 2015-03-19 |
20150078567 | Varying Adaptive Filter Step Size in Acoustic Echo Cancellation - A method and system for acoustic echo cancellation varies a step size of an adaptive filter in an acoustic echo canceller. Far-end data is received and echo estimate data is calculated using the received far-end data. Microphone data is received and error data is calculated using the received microphone data and the echo estimate data. A first average of the microphone data and a second average of the error data are computed over a predefined number of samples. An echo leakage is estimated using the first average and the second average wherein the echo leakage indicates an extent to which the far-end data is present in the error data, and the step size of the adaptive filter is varied based on the echo leakage and a maximum allowed step size. | 2015-03-19 |
