+1 for more docs with some practical examples

As far as I understood from the docs, noise suppression is applied automatically only with VepAecBeamformingNode. Well, technically, NS is also present in HybridNode. But the former is based on Alango algorithms, and the latter - on WebRTC lib. I remember a thread here, where someone mentioned that the former is more accurate.

You can take a look at existing examples. I tried to record input audio stream w/ and w/o VepAecBeamformingNode, and there was a big difference in terms of the noise level.
