Gustaf Ullberg 09226fc832 Disable high-pass filtering of the AEC reference ... Currently the echo canceller reference signal is high-pass filtered to avoid the need of modeling the capture-side high-pass filter as part of the echo path. This can lead to the lowest frequency bins of the linear filter diverging as there is little low-frequency content available for training. Over time the filter can output an increasing amount of low-frequency power, which in turn affects the filter's ability to adapt properly. Disabling the high-pass filtering of the echo canceller reference solves this issue, resulting in improved filter convergence.
