I know. But not using a mic shows the noise in its "cleanest", most
stable state. If I turn on the connected microphone the "aliasing" is
still there - I have heard it in between loud sounds, and I have
heard it "on top" of quiet sounds.
Using a Sony ECM-MS957S, btw.

Thanks for the tip.
I just find it strange that comparing my "mic-connected-but-turned-
off" recordings with similar recordings from a Sharp MT-290 produces
results in favour of the latter - which doesn't have
the "aliasing"/quantising-like noise in the mid-range.
Oivind.
