Microsoft sliders

[Dirk Bruere at NeoPax]

On the standard volume control popup does anyone know what the Play
Control, Wave, Line In sliders represent in terms of dB? ie what the
max (and min?) are?

Undefined. The window you see is just the generic MS
Win code which passes values to the sound sub-system.
It is up to the sound drivers and hardware to interperet
the level setting values to whatever. And that is typically
undefined, also.

Even if you characterized them, since there are no practical
markings nor any numbers to see, you would have no way
of adjusting any of the controls to any particular setting
anyway. Why do you ask?

They appear to behave as linear pots, ie. half way down is within a
furlong and a half of -6 dB.

But everything audio in windows seems to me to be left undocumented. I
was at a pre-intro of some new OS that comes out real soon now, the guys
that demoed it carefully mentioned that it was law-obedient, but were
igoorant about the treatment of premium content, it appeared however to
be the first time they ever encountered that magic wording. Sad, because
I had hoped they could explain it ...

Microsoft can't "label" or "calibrate" those controls.
They are generic and used by literally hundreds of
different vendors and products of audio hardware.

The hardware vendors could do it if they really
wanted to, but there appears to be no viable
market for it.

I've never found 2 applications that appear to deal with them the same way.

Have you checked out the limitations on media content in Vista btw ? Like
disabling s/pdif outputs for example.

There's an "AC 97" audio spec for computers running Windows you
could google for (the number indicates it's 10 years old), but as
others said, there's likely nothing on the scaling of those virtual
sliders, except that full up is full on, and full down is mute/off
(which could be -60dB, or whatever the bleedthrough might be on
whatever computer/soundcard you're using).

As was written of DRM - "the longest suicide note in history".
