Almost all mixers go up to +10dB, some +15, some +20.

We are talking about per-strip meters here. In the
HW days most mixers wouldn't even have those - maybe
just an 'overload' led if you were lucky.

In Ardour they are also used as recording level meters,
but apart from that they are mostly useful as 'signal
presence indicators' or to provide a quick visual hint
of from where (from which strip) some part of a mix
originates. There is no need for a 'standard' meter
in these functions. 

Meters with a 'standard' scale that enables you to learn
unconsciously a relation between a visual indication
and what you hear (that is to only real reason for having
a meter scale standard), are required for mixing, mastering
and in broadcasting, but not for individual tracks in a DAW.
So in a DAW strip you can just ignore standards and make the
fader and meter scales the same if they are side by side. 

What Ardour is lacking is sort of 'monitoring' window,
a place where you can select in a convenient way what
you hear, and how. Anything you do here should never
affect the 'program output' whatever that is, normally
the Master strip out.

*This* is the place to have a 'standard' meter, the
one you use for mixing, mastering, etc.
Such a monitoring module should switch automatically

- A signal selected by the user, normally this will
  be the Master strip output, but it could also be an
  external signal such as the output of a mastering
- Auditioning when active.
- Solo (not-in-place) when active.

It should also provide switching between different
monitor outputs (each with its own volume control).
It's also the place to integrate things such as
talkback (which requires dimming the monitors).



Io lo dico sempre: l'Italia è troppo stretta e lunga.
