Hello, is there a way I can dynamically modify sox effects while sox is
running? I want to have a way to add effects to my voice (pitch
modulation/reverb/etc.) and pipe that to OBS and Mumble. Is there another
application that does this?
The current command I am using is:
sox -t pulseaudio default -t pulseaudio null reverb pitch ...
Then I record from Null Source using pavucontrol.

Not natively in sox. I use separate processes for
decoding/effects/playback and manage the command pipelines and
sox processes.
I wrote/use dtas (duct-tape audio suite) to do pipes and process
management:
git clone https://80x24.org/dtas.git
Specifically dtas-player; which allows YAML files pointing to
ruby (or shell) scripts which can be edited and auto-reloaded
via inotify (see examples/splitfx.sample.yml ).
You may also use dtas-sourceedit or dtas-sinkedit to edit
the commands used for sources/sinks independently (which
affects all files you play). I made the splitfx YAML stuff
later to have per-file effects.
Some basic docs are in the Documentation/ directory; but it's
been a while since I updated it... I use dtas every single day
for the past few years for general music listening :)

Since several years I use a solution which should be finally ported to
the recent SoX version as a separate program but I lack time to do it.
My current solution is a patch to run SoX full screen, interactively,
with ability to modify speed and volume and jump through the recording
easily with simple key-strokes. Other interactive modifications could be
added easily in the code. Not many formats are seekable in this version,
I use WAV.
How the window with my interactive SoX looks like:
sox Version 12.17.9, interactive sox v. 20070202rzm

CDP, which since a few years is an open source software and available
for all three major operating systems.
https://www.composersdesktop.com/
and
http://www.unstablesound.net/cdp.html
Its syntax is quite similar to sox and the two make good command line
companions. CDP has the ability to read in a textfile in place of some
command line arguments. These textfiles are breakpoint files and contain
time-value pairs which you write yourself.
