    • Low latency and computationally efficient techniques may be employed to account for errors in data such as low bit-width, oversampled data. In some aspects these techniques may be employed to mitigate audio artifacts associated with sigma-delta modulated audio data. In some aspects an error may be detected in a set of encoded data based on an outcome of a channel decoding process. Upon determining that a set of data may contain at least one error, the set of data may be replaced with another set of data that is based on one or more neighboring data sets. For example, in some aspects a set of data including at least one bit in error may be replaced with data that is generated by applying a cross-fading operation to neighboring data sets. In some aspects a given data bit may be flipped as a result of a linear prediction operation that is applied to PCM equivalent data that is associated with the given data bit and its neighboring data bits. In some aspects a set of data including at least one bit in error may be replaced with data that is generated by performing linear interpolation operations on PCM equivalent data that is associated with neighboring data sets.
    • 可以采用低延迟和计算有效的技术来解决数据中的错误,例如低位宽度,过采样数据。 在一些方面,可以采用这些技术来减轻与Σ-Δ调制音频数据相关联的音频伪影。 在一些方面,可以基于信道解码过程的结果在一组编码数据中检测到错误。 在确定一组数据可能包含至少一个错误时,可以用基于一个或多个相邻数据集的另一组数据替换该数据集。 例如,在一些方面,包括至少一个错误位的一组数据可以由通过对相邻数据集应用交叉衰落操作而产生的数据代替。 在一些方面,作为施加到与给定数据位及其相邻数据位相关联的PCM等效数据的线性预测操作的结果,可以翻转给定数据位。 在一些方面,包括至少一个错误位的一组数据可以由通过对与相邻数据集相关联的PCM等效数据执行线性内插操作而产生的数据代替。

    • The rate at which data is provided by one device and the rate at which that data is processed by another device may differ. For example, a transmitting device may transmit data according to a transmit clock while a receiving device that receives the transmitted data may process the data according to a receive clock. If there is a timing mismatch between the transmit and receive clocks, the receiving device may receive data faster or slower than it processes the data. In such a case, there may be errors relating to the processing of the received data. To address timing mismatches such as this, the receiving device may delete data from or insert data into the received data. In conjunction with these operations, the receiving device may modify the received data at or near the insertion point or the deletion point in a manner that mitigates any adverse effect the insertion or deletion may have on a resulting output signal.
    • 一个设备提供数据的速率和另一个设备处理该数据的速率可能不同。 例如,发送装置可以根据发送时钟发送数据,而接收发送的数据的接收装置可以根据接收时钟处理数据。 如果在发送和接收时钟之间存在定时不匹配,则接收设备可能比处理数据更快或更慢地接收数据。 在这种情况下,可能存在与接收到的数据的处理有关的错误。 为了解决诸如此的定时不匹配,接收设备可以从接收到的数据中删除数据或将数据插入到数据中。 结合这些操作,接收设备可以以减轻插入或删除对结果输出信号可能产生的任何不利影响的方式在插入点或删除点处或附近修改接收到的数据。
