Without the hiss and buzz, all would be perfectly acceptable for Zoom

The level - or levels - surprised me, since despite their slight differences
what they have in common is that they're all very low. That comparison
recording was made with Audacity, which needed its input sensitivity to be
at maximum to capture any appreciable signal at all.

Am I overlooking a Windows 7 master-setting for incoming audio? I've
certainly no recollection of ever seeing one.
