Abstract: Audio and haptic signal processing systems and methods are provided. There is provided a method for haptic drive signal generation. The method comprises receiving an input audio signal for driving an audio speaker. The method further comprises deriving, from the audio signal, data components indicative of behaviour of the audio speaker when being driven by the input audio signal, each data component being associated with a respective frequency range. The method further comprises determining a haptic drive component from each data component. A gain is selected to provide to each of the haptic drive components, the gain being selected for each respective frequency range. Each selected gain is applied to the respective haptic drive component to produce gain adjusted haptic drive components. A haptic drive signal is determined from the gain adjusted haptic drive components, the haptic drive signal being so as to produce a mechanical behaviour of the haptic actuator when the haptic drive signal is used to drive the haptic actuator

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value based on previously received audio packets, to identify a receive time of a first audio packet of a talk spurt, to determine an offset value of the first audio packet based on the receive time and the arrival delay value, and to adjust a target delay value associated with a de-jitter buffer based on the offset value. The apparatus also includes a de-jitter buffer configured to buffer the first audio packet based on the adjusted target delay value.
