![]() ![]() The digital audio samples are saved in capture buffer 130 sample by sample. In the capture stream path in the figure, an analog to digital (A/D) converter 120 converts the analog sound mic(t) captured by microphone 110 to digital audio samples continuously at a sampling rate (fs mic). The far end of the two-way communication system is exactly the same. ![]() The example near end 100 includes a capture stream path and a render stream path for the audio data in the two directions. 1, an Acoustic Echo Cancellation is used to remove echo of the far end user's voice. With reference again to the example near end 100 of a typical two-way communication system illustrated in FIG. for suppressing echoes for one or both directions of traffic using echo cancellers ![]() H04M9/082- Two-way loud-speaking telephone systems with means for conditioning the signal, e.g.for suppressing echoes for one or both directions of traffic H04M9/08- Two-way loud-speaking telephone systems with means for conditioning the signal, e.g.H04M9/00- Arrangements for interconnection not involving centralised switching. ![]()
