Giant bug noises

I understand, vaguely, how human voices vary with the overall size/shape of the individual(s vocal chords), and I can use that to make reasonable assumptions about what the voice of non-human fantasy race of oversized (giants), or undersized (gnomes, fairies, etc.) humanoid race might sound like compared to a 'standard' human voice.

But I do not know enough about the noises bugs make for me to be able to confidently make similar assumptions about how their communication noises might change when the animal is scaled to a fantasy sized variety.

What differences would be expected in the noises made by bugs, if they were scaled up to giant versions of themselves?

Details, specifics, limitations, etc. :

1. how/why do these giant bugs exist? Handwavium, they just do. These are not an evolution from real species to fantasy species, they are not a fictional species independent of existing animals, they are the actual existing species just bigger. Ignore any issues caused by the square/cube law thing, except maybe to handwavium increase structural integrity of body parts to support new size, no new materials allowed, no new structural organization of parts and materials, they just are strong enough to be bigger because handwave.

2. "Noises" = sounds produced by the bug, and only the bug, for the purpose of communication. This can include mating calls, noises to try to scare away predators, noises to cooperatively hunt or other social needs, etc. Incidental noises, such as buzzing of wings during flight, or footsteps (or multiple legs contacting each other) as they walk, rubbing against objects in their surrounding environment, etc. don't count. If the bug uses other objects from the environment to produce the sound (such as a wolf spider vibrating leaves) that doesn't count either.

3. "Bug" = Insect, Spider, Scorpion, or Centipede, unless you can make a very convincing argument for something else that might be called a "bug" by a layman. Some specific examples of the type of thing I'm referring to are cricket chirps (probably the most obvious and recognizable bug noise of all), hissing-cockroach hiss, "barking" or "Whistling" spider (Selenocosmia crassipes) hiss, Flag tail centipede (Alipes grandidieri?, others?) hiss.

4. "Giant version" = Let's say approximately the height/length/girth/weight of a large breed of dog, like a St. Bernard. EDIT: Think ": Honey I Shrink the Kids" technology, not evolution or alien physiology, but rather the exact identical real-life animals just scaled up completely, proportionately, and in every aspect. Obviously, many "bugs" are not the same proportionate shape as a dog, so modify as needed within the spirit of the question, exact measurements shouldn't create enough of a difference in the answer to nitpick unnecessarily. In other words, I don't feel like (for the purposes of this question) there would be a significant difference in the sound made by an 6 foot long centipede compared to a 10 foot long one, regardless of whichever of the two might be closer to 'dog-sized' by weight or width or whatever, as long as we don't get out of hand and start discussing what it would sound like if it were as tall as a car and longer than 2 buses. Use best judgement, common sense, reason, when trying to apply 'dog-size' to something that is not 'dog-shape'. Other than size, nothing else about the animal should change, or should change as little as possible to accommodate any complications that might otherwise arise from the added size (no mammalian lungs/vocal chords or any similarly radical change, only increased size of whatever they used before to make their noises originally, and as little structural change in those as possible to support the additional weight/volume/etc.).

5. "differences" in the noises = Pitch and Volume are the two most obvious here. Would the sound have the same pitch, but just be louder, or vice versa? Or would the pitch change so much, that it becomes separate intermittent clicks or impacts, rather than a tone or pitch at all? Would Duration change while pitch and/or volume stay the same? Would the sonic texture change, from seemingly one sound source to multiple sources?

For those of you who didn't know, and/or don't believe, that spiders make such noises, here's an example(WARNING to those who are creeped out by such things, it's creepy)
