Cakewalk can record in 16, 24 and 32 bit. Its internal
audio processing
engine defaults to 32 bit - a separate setting than recording bit depth -
thus the real-time conversion CPU hit. I read that most modern DAWs process
audio at 32 bit internally nowadays. I know that Cakewalk, Mixbus and Reaper
do - not familiar with any others. Cakewalk does have another audio engine
setting which puts the engine in 64 bit, but I want it all the same if
possible.
I think you're getting something conpletely wrong here. Your interface will send
integer values to your computer - this is where the bit depth really matters since
a higher bit depth allows for more sloppy/careless input gain control (i.e. you can
record at a relatively low input gain and still get "enough bits" after
normalizing
the signal).
My audio interface defaults to 32 bit. I want the
interface, engine, and
recording all to be in 32 bit.
Your DAW (like any DAW currently on the market) internally stores/processes audio data
with 32bit _floating point_ values (which are totally different from integers). This
prevents
both clipping and rounding errors during sound processing.
There is a debate as to whether this is
overkill, but I have the HDD space, and I really dig the fact that it's
impossible to clip 32 bit, basically. What would be a ruined recording in 24
bit, I can just volume automate or compress. It sucks to lose a hot take due
to one loud rouge sound.
The 'overkill' argument you most likely encountered was most likely talking
about
the bit-depth of your output. Anything above 16 or maybe 24 bit _is_ overkill, unless you
produce for mebers of the Elephantidae species ... :-)
I am using the GUI "Jack Control" thingy. It
makes routing a breeze. I see
no bit depth option anywhere. I was hoping there was a command-line option.
I'll keep fooling around with it, and if I find a solution, I'll post back
in case someone else has the same issue. More & more interfaces are doing 32
bit. I know the argument that the DACs are only around 24-bit spec usually
but again no CPU hit from real-time conversion.
What realtime conversion? Your DAW is converting integer samples to float, no matter
what you do.
