Fons Adriaensen escribio:
If you export to an integer file format anything above
0dB will
be clipped.
OTOH, if the export includes resampling then the peaks in the
exported file will be higher than those at the output of the
master strip. The difference will be small in most cases, but
in theory it is unbounded. Better keep a dB or so of headroom.
My 2 cents:
Keep -0.2db headroom minimum, or for the lazy/cautious: a peak limiter set at -0.2db on
the master buss should do the trick. (I'm not a good engineer, so I fall into the
second category).
-0.2db seems to "hold" it's value better in most software that resamples.
Anything higher will almost always end up clipped or limited, in an uncontrolled fashion -
as Fons pointed out here, some peaks will invariably be sampled on either side and the
software will just pin everything between the samples at 0db. Yuck.
I spent an afternoon last year comparing -0.2/-0.1/0.0db max, and I found this to be the
case almost every time. Never had a stray peak at -0.2db
