摘要： Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

摘要： Embodiments of packet loss concealment for phone-to-hearing-aid streaming are generally described herein. A method for packet loss concealment can include receiving a first frame at a hearing assistance device, determining, at the hearing assistance device, that a second frame was not received within a predetermined time, and determining a first set of sequential samples that match the first frame. The method can include cross-fading the first frame and the first set of sequential samples to create a first cross-faded frame and extrapolating a third frame to replace the second frame using the first set of sequential samples and an autoregressive model.
