Hello,

when I want to create a analysis file to use with pvoc, for instance, I
prefer to run Csound by Terminal as it's much more comfortable and allows me
to process in parallel several audio samples. The same if I need to run a
csound file using pvoc or other FFT opcodes. 

In order to create a .pv file I write in the Terminal:

cd /Volumes/.....
 PATH=$PATH:/usr/local/bin
pvanal -n8192 -w16 -c1 Sample1.aif Sample1.pv

The question is: where can I set the sample format if I use Csound via
Terminal? is there a command line I need to add to the previous one? because
the default sample format is 16 bit. 

I have the same problem rendering via Terminal a csound file using pvoc or
others opcodes. 
For instance the command line for the Terminal is:

cd /Volumes/........
 PATH=$PATH:/usr/local/bin
 csound -A -o pvcross_a12.aif pvcross_a.csd

Even if I process a 24bit or 32bit .pv file the pvoc output will be always a
16bit sound sample. 

This is something I already in the past discussed with you, but
unfortunately it's still not really clear to me.
Thank you!

I do not follow.  .pv files are in floating point or doubles.

i don't think i understand this one. as far as i know, pv files are doubles
(or eventually floats?), and that has nothing to do with the bit depth of
the audio files. am i right?

again, this is something completely different. if you want to render to a
24-bit sound file (using pv opcodes or not), use the -3 flag:

http://csound.github.io/docs/manual/CommandFlagsCategory.html

i guess you can render to 32-bit sound samples with the --format flag? but
i have no idea, never used 32-bit. i don't even know of true 32-bit DACs.
anyone?

Everything is clear, thank you.
