For me it's driving while under the influence. If you couldn't tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can't fathom. I've only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.

I took an audio focused CS course in university and for my main project, I evaluated, among other things, the sound quality of various cables and a distortion pedal I had. None of the cables made a noticeable difference, same thing with the pass through mode on the pedal. I didn't set up a crazy long daisy chain to find out if they eventually did make a difference, but I bet even then it wouldn't be a big deal.

And for digital, it's even less so because you need a lot of error before you start mixing up 0s and 1s.

I've, in my own limited ability, looked at 50m of guitar cable verses 3 and seen a drop off in higher frequencies. Basically lost the "sparkle". Might depend on the cable and other factors though. You put a sine sweep through the signal chain to test it

It's been a while so I don't remember the specifics exactly, but I believe I used a square wave because it's easier to see frequency dropoff. The more that gets dropped (at least at the high end), the rounder looking a wave you'll end up seeing.

Now I'm wondering what happens if I use a square sweep to generate an IR on a guitar cab.... 🤔

[-] Buddahriffic@lemmy.world 2 points 7 months ago

I don't know if it needs to be a sweep, even. A square wave technically includes all frequencies to create that instant rise and hold because a freq high enough to rise that fast will also drop immediately after so a slightly lower frequency is needed to cancel that out, which then needs a lower one to cancel it out and so on. So you can see right away just by looking how well the square shape is maintained if all of the frequencies are making it through. If the corners look more rounded, then high frequencies are being lost. If the flat part looks bulgy, low frequencies are being lost. If the flat part looks squiggly, mid-range frequencies are being lost.

Though it is more of a rough brute force approach and a sin wave sweep will give a better idea of specific frequency response.

And I should correct what I said earlier, it wasn't that none of the cables were dropping anything, but that they all looked similar in what they were dropping and there wasn't much of a difference between a 10cm patch cable, a $2 3m cable, or a $30 3m cable.

If I ever get the space to set it up I might try it all out. I managed to get an IR out of the noise someone's guitar pedal made on a record.
