发明名称 AUDIO DATA STREAM SYNCHRONIZATION
摘要 Systems and methods of synchronizing an input signal and an output signal via employing a sampling component that samples a speaker output and a microphone input during a full duplex communication, at a same clock frequency and same exact time to supply time synchronized sample signal(s). A software acoustic echo canceller (AEC) can then provide for production of a reconditioned microphone signal, wherein the speaker signal is absent therefrom. The time synchronized samples can be processed by the software AEC, in general without real time constraints that can be imposed by the operating system (OS).
