Sorry, just got around to listening to that. The AEC indeed does a
pretty good job at that file. As you mention, it's indeed important to
have low-distortion loudspeakers. I think the noise suppression is (by
default) a bit too aggressive. It would probably be good to reduce the
noise/echo attenuation parameter a bit.
