Currently, FFT is performance when AEC buffers farend signal. This has some drawbacks 1. memory inefficiency: two ring buffers are needed; 2. computation inefficiency: if ringbuffer gets wrapped around, some FFT computation will be wasted; 3. accessibility: the main AEC function looses accessibility to the time-domain signal. Therefore, this CL tries to buffer time domain data, which is buffered any way if a debugging macro is defined, and calculate the FFTs where they are actually used.
