James,
I find an easy approach is to write the signal out as alternating i/q
binary if it's not already. That can be read into audacity as stereo
(File -> Import -> Raw), edited and written back out as raw data without
header (File -> Export -> Export Multiple, and choose Raw Headerless).
Don't worry about audacity's sample rate because you're editing raw i/q
anyway. This allows editing down to the sample level.
Good luck!

I'm receiving a phase modulated signal representing a periodic pulsed
byte that looks something like this:

I'm trying to understand how I might split this signal roughly halfway
between each pulse of activity so I can save each pulse as a separate IQ
fil, bit like this:
------|-|||--||------
-------|||--||||-------
------|--||||-|------
The split does not have to be precise, it only needs to avoid bisecting
any of the pulses. Here are some things I've tried.- Creating a custom
block on the receiver that uses a timing interval. Unfortunately, the
pulses aren't perfectly periodic so eventually this causes the split to
drift.[...]
