Mike --
More questions about your suggested changes to the noise-level metering
function and the associated widget.
Why should we prefer a peak-reading to average-power-reading meter?
The preferred level of 30 dB is for average, not peak. That's the
average noise level with no significant signals present. Especially if
there are broadband noise spikes present, I don't want the meter
responding to them any more than necessary. And we already had a
(sort-of) peak-hold indicator, right?
When real signals come on, on a crowded band, the level may go much
higher than 30 dB.
It's fine to change some color to red when some raw (absolute-value)
samples get larger than (say) 20000, or the rms is less than (say) 10.
And I think it's right to make the gain slider NOT affect the reading of
the level meter.
Why do you want the dB numbers displayed on both the status bar and just
below the thermometer?
