摘要： An electronic device for reconstructing a lost packet in a Sub-Band Coding (SBC) decoder is described. The electronic device includes a processor and instructions stored in memory. The electronic device detects a lost packet, obtains a zero-input response of a synthesis filter bank and obtains a coarse pitch estimate. The electronic device also obtains a fine pitch estimate based on the zero-input response and the coarse pitch estimate. The electronic device selects a last pitch period based on the fine pitch estimate and uses samples from the last pitch period for the lost packet.

摘要： A communications device that is configured to detect double talk is described. An echo canceller is configured to cancel an echo from an input signal using an adaptive filter. A double-talk detector provides a double-talk statistic. The double-talk statistic is proportional to the ratio of the remaining echo energy in the cancellation error signal and the total cancellation error energy.

摘要： In a particular embodiment, a method includes dynamically adjusting a clock rate to one or more hardware components within a mobile device during a silence period. During the silence period of a video telephony call, when a user of the mobile device is not speaking, the mobile device monitors the background noise and compares detected background noise data to previously detected background noise data to determine changes in the background noise. If the comparison shows that the change in background noise does not result in a change in background noise conditions or does not exceed a difference threshold, the clock rate to certain hardware components may be reduced and portions of certain hardware components may be powered down. The mobile device may send previously stored background noise update packets.
摘要翻译：在特定实施例中，一种方法包括在静默期期间将时钟速率动态地调整到移动设备内的一个或多个硬件组件。在视频电话呼叫的静音期间，当移动设备的用户不说话时，移动设备监视背景噪声，并将检测到的背景噪声数据与先前检测到的背景噪声数据进行比较，以确定背景噪声的变化。如果比较表明背景噪声的改变不会导致背景噪声条件的改变或者不超过差值阈值，则某些硬件组件的时钟速率可能会降低，并且某些硬件组件的某些部分可能掉电。移动设备可以发送先前存储的背景噪声更新分组。

摘要： Mid-side (M-S) encoded audio is reproduced by a device that includes a multi-channel digital-to-analog converter (DAC). The DAC has a first channel input receiving a digitized mid audio signal, a first channel output providing an analog mid audio signal, a second channel input receiving a digitized side audio signal and a second channel output providing an analog side audio signal. The DAC may also include a third channel for receiving a digitized second side audio signal. The second side audio signal is phase inverted. The device may be a handheld wireless communication device, such as a cellular phone, and may also include transducers for outputting M-S encoded sound in response to the analog mid and side audio signals.
