Make it possible to click the bus peak label to reset it.
Steinar H. Gunderson [Sun, 28 Aug 2016 21:18:58 +0000 (23:18 +0200)]
When the fader is moved, interpolate its volume over the next frame.
Faders are among the things one should definitely be allowed to move
around during an actual mix without hearing clicking; the gain and threshold
is maybe somewhat less so, so I won't give it the same treatment, at least not
right now.

Show historic peak of each bus under the peak meter.
Steinar H. Gunderson [Sun, 28 Aug 2016 15:49:23 +0000 (17:49 +0200)]
Replace the R128 meters for each channel with a digital peak meter.
R128 is a superior way of measuring loudness, but for each bus, we care more
about getting the recording levels right (ie., that we don't peak) than loudness.
Since we do our mixing in float, unlike a typical digital mixer, it's not as
critical (at least assuming that the limiter is on and will save us later in
the mastering chain), but it's probably better to be consistent with convention
here.
Thus, use a simple digital meter for each bus, even though we of course still
use R128 for the mastering section.
