发明名称 Bi-directional asynchronous telecommunication audio signal processing
摘要 An apparatus is provided for digital signal processing of telecommunication signals along respective transmit and receive paths of a two-way telecommunication link. The respective transmit and receive signals each include an audio data component and a timing component. Digital signal processing of at least one of the signals, such as an echo cancellation, employs information derived from the audio data component of the other signal. To compensate for differences between the respective timing components of the signals, resynchronization of each signal in terms of the timing component of the other signal is performed prior to modifying the audio data component of the other signal.
