OK...I'll do it that way. So the idea is that the colors represent peak
values then but the meter is noise. That works.
15dB peak value though is something like 5dB RMS on my system. Shouldn't
that be a fair bit higher for a warning? Peak will alway be well above noise.

Mike --
I'm trying my best to make good use of your recent hard work on coding.
I think if you change the level-meter portion your "cumulative.patch" in
the following ways, it will be an improvement to the program:
1. The definition of dB level should remain as it is now, namely
pxdb=20.0*log10(rms), and the meter should display that number.
2. The slider should not affect the meter reading.
3. The meter range can be increased to 0-90 dB.
4. symspec() can return a "pxdbmax" value, as well as the pxdb value.
5. In symspec(), the statement
if (x1.gt.abs(pxdbmax)) then
should be changed to
if (abs(x1).gt.pxdbmax) then
6. Warning colors may be displayed on the level meter if pxdb<15
(yellow?) or pxdbmax>85 (red?).
