what is a DSP node and can I hide any that are shown?

[cynaraos]

for pretty much the entirety of my playtime in Garry's Mod, I've had DSP nodes show up in maps that I play in. I do not like the obsolescence that I see in them, and as the title of my post suggests, I want to know if I can hide any DSP nodes I see.
here is an example of a DSP node, if you require it:

Note sure how relevant this is, but a quick google pulled up this thread which is clearly the same problem. Try some of the stuff people suggest in the comments.

You can try these commands as well:

dsp_off 1
adsp_debug 0
dsp_automatic 0

If you care to know DSP in this context typically stand for Digital Signal Processing and likely has to do with processing audio depending on where you are in the map. Should sounds be echoed in a large room? Should outside sounds be muffled and put through a low pass filter? Etc.
