Did you look at the manual? In its simplest form, sox uses - to denote
reading from stdin and/or writing to stdout. See the section on
"special
filenames".
Moreover the description of the -p option says
−p, −−sox−pipe
This can be used in place of an output filename to specify that the
SoX command should be used as in input pipe to another SoX command.
For example, the command:
play "|sox −n −p synth 2" "|sox −n −p synth 2 tremolo 10" stat
plays two ‘files’ in succession, each with different effects.
−p is in fact an alias for ‘−t sox −’.
Note the last sentence, which sets -t (as described in the special
filenames text) and also has a following "-".
I'm trying to build an application at the moment, where serial sox pipe
processes could be used in many different ways.
It would help me to understand what you're trying to do if you explained
whether you want just to process a single source file (ie something that
already exists) or if you're trying to take continuous incoming sound
and
do something to it.
Are you trying to make multiple copies of that source and send each of
them somewhere else, possibly with different effects applied to each
one?
Are you hoping, if the destinations are playback devices playing in real
time, that the sound playing at each one will be in-sync with each
other?
Are you expecting the playbacks, if there are any, to be in a known sync
with the input (ie delayed by a predictable number of mS)?
For instance, I'd like to
eventually make something similar to the MC system
<https://docs.cycling74.com/max8/vignettes/mc_topic> in MaxMSP.
You may know what you mean, but I don't. That page is too
general/vague.
What /specific/ thing are you trying to do?
