摘要： Methods for concealing audible distortions resulting from changes in jitter buffer size include receiving an audio stream, storing the audio stream in a jitter buffer, and determining a pitch period associated with the audio stream. To expand the jitter buffer, a method includes inserting additional audio data that has a duration corresponding to an integer multiple of the pitch period into the audio stream. To contract the jitter buffer, a method includes removing a portion of the audio stream having a duration corresponding to an integer multiple of the pitch period.

摘要： Private message system, method, and apparatus are described. A private message that includes encrypted data and identifying information indicating a recipient client device authorized to read the private message is stored at a server computer. Since the client devices perform all encryption and decryption processing, the server computer stores the private message in a platform agnostic manner and without performing any encryption/decryption related processes. Although any number of recipient devices can receive the private message, only a recipient client device authorized in accordance with the identifying information can read the private message.
摘要翻译： 描述了专用消息系统，方法和装置。 包含加密数据和指示被授权读取私人消息的接收方客户端设备的标识信息的私人消息被存储在服务器计算机中。 由于客户端设备执行所有加密和解密处理，所以服务器计算机以平台不可知的方式存储私人消息，并且不执行任何加密/解密相关过程。 虽然任何数量的收件人设备都可以接收私人消息，但只有根据识别信息授权的接收方客户端设备可以读取私人消息。
