Hi Rob,
wow, just 1% bit depth saturation? Can't you crank up the signal, or do you=
deal with
signals so dynamic that you hit 0 dbFS if you boost them? That would be a d=
ynamic range
of more than 120 dB or so.. If remember correctly 24 bits-files have a sign=
al-to-noise
level of almost 140 dB!
Yeah, for people who own those MS -> ST mics it's definetly good to know th=
ey can still
access the discrete M and S channels.
I have another question but I'll make it a new post since the top is differ=
ent..
greetings,
Max
