Here's a step by steps as a solution.

1. Prepare Your Sound File
Get your audio file This can be any sound you want to use.
Convert to WAV The sound must be a 16-bit WAV file and bitrate at 44100. You can use a program like Audacity to convert your audio to this format and set the correct sample rate.

2. This is typically at "YOUR_PARTITION"\\Steam\\steamapps\\common\\GarrysMod\\garrysmod on Windows. Create the sound folder

3. If you don't already have a sound folder in the garrysmod directory, create one.
Create the ui folder Inside the sound folder, create a folder named ui. Add your sound Place your prepared WAV file into the garrysmod/sound/ui folder. For a more organized approach, you can place it in a custom addon folder.

3. (RECOMMENDED) Restart Garry's Mod
Close and reopen the game for the new sound to be loaded and applied.

Hello STRESSED CAT IN A BOX and Adi DK I'm adding your guy's or gal's own mod to Unreal Tournament for Garry's Mod because this mod allows me (Even at default setting) to include UT4 hit sounds and most importantly I have to follow the research and it obliviously worked since your guy's or people's comments didn't let me follow it correctly but the AI did helped me follow its own steps.

ah

That’s a good idea! Out of any of my workshop uploads, this is probably the simplest suggestion I’ve received yet. Probably?

Uh IF it’s a custom hit sound, you could try increasing the volume of it in audacity. Although that would make it UNIVERSALLY louder, so if you shoot a quiet gun it’s gonna be loud instead.

I think it would be better if you can make it louder or something like that
Because my weapons are louder than the hitmarkers themself

it didn't work ;(
the file path i put in is example.wav

so did it work...? if it didn't, copy paste the filepath you inserted into the text box into a comment here, you may have added an unnecessary sound/ in front of your audio file's name

thanks, i will try it out and see if it works. and btw, no sound was playing at all
edit: done and it was 44100hz. is it correct hz? also slider is 0

I don’t think you mentioned it and I forgot to ask, is NO SOUND playing or a DIFFERENT KILLSOUND playing instead? If a different sound is playing, set the audio preset thing (the slider either values between 0 and 5) to 0.

Oh and the setting that disables the killsounds and hit sounds entirely is likely a slider (or check box?) inside the Utilities tab within the spawnmenu, on the right side of the screen? It’s been a while since I checked it out, but it should be

Audacity can also be used to change the sound’s frequency/rate btw, if that wasn’t easily guessable

The console will tell you if something is wrong with the audio, and if it doesn’t you should try writing “developer 1” into it to make it spot out more info.
Uhhh you could see the rate in a program like Audacity. The console can also tell you if the game’s trying to read a file with an incompatible frequency instead of 44100hz, as mentioned prior.

48000hz is a bit of a standard for audio quality nowadays? but uh- be careful while changing it to 44100hz cuz it will make the audio slower without correcting the speed back to normal!

okay. question, how do i check if its 44100hz, and what enables/disables it? and info: i downloaded sound off of a website and it is mp4, then i changed file to wav.

if it's your custom sound specifically that isn't working you're likely on the wrong setting.
However, if all of them don't work you likely disabled it entirely in the menu.
Another possibility is the uhhh rate of sound being wrong...? has to be 44100hz or smth, or it won't play properly.

why doesn't the kill sound work? i did everything the comments below me said. i put my kill sound in C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\sound. is there something else i need to do for it to play the sound when killing?

works well now, many thanks

will try

I am not entirely sure, but if it has sound/ in front of it in the setting, try removing it so that it’s just markpinga.wav

what’s the setting set to? Like what did you write into the textbox setting in-game :P

steamapps/common/GarrysMod/garrysmod/sound/markpinga.wav is the file path

btw, gmod doesn't use the custom folder at all, it doesn't load. If you are using that, rename custom to addons and it should work fine :P (if it asks you to merge with the existing foler, do that)

alright... so, what folder is it in?
starting from steamapps/common/GarrysMod/garrysmod, what's the filepath?

keeps saying "Failed to load sound "sound\markpinga.wav", file probably missing from disk/repository" even though i have done everything step by step

No, if I remember correctly it relies on server and client communication.

is this client side

try add Randomize killsounds and randomize hitsounds

this addon is good, i liked it. I set the Hitman headshot sound and it's so satisfying tho. But it didn't work for me at first. The problem was if you put your custom sound in "sound" folder, and set a path "sound/customsound" this didn't work. So, as i figured, to make this work, you have to create the "ui" folder in the "sound" folder and put your sound in the "ui" one. Then in utilites your file path should be "ui/customsound", where customsound is your sound file name.

it works perfectly, thanks for make this addon, I want this addon for quake III arena hitsound

wdym where exactly? ah whatever, i'm just used to modding the source engine by now.. so i've gotten good at it...
SO.
go to your gmod files (right click on gmod in your library, click browse local files or whatever)
and then go to the folder garrysmod
then enter the folder sound (if it isn't there, make a folder named sound) NOT SOUNDS, do not put an s in sound
then paste your custom sound file in there
keep in mind it has to have frequency of 44100 hz or whatever if you make it yourself
now just go into the utilities menu (hold q, click utilities) in-game and set the text box to the sound path of your sound
If your sound is named customsound.wav and it's inside the sound folder, input sound/customsound.wav
remember to set the slider to 0, for it to be a custom sound.
If anyone doesn't work, let me know. I should probably record a tutorial... though it's a little late, this addon is pretty dead.

where exactly? imma need a step by step instructions.

you just have to make a new folder.

where do I put the custom kill sound? where's the ui thingy?

cuz i want something simpler

can you make a warzone enemy downed sound

also i you didnt asnwer my other qustion

it has to be placed within your gmod sounds folder somewhere.. i should make a tutorial for it.. later, though.

i cant find the path file for it

thats what i mean

You're supposed to do it yourself, that's kinda the whole point of the addon. The custom sounds don't use links, they use filepaths.

also can you make an addon warzone enemyd down sound?

yeah but i dont know the link thing to the killsound i want

what? you'd have to set it as your custom killsound probably...?

btw how do i turon on warzone enmeny downwed sound

in testing the thing im trying to test
it doesnt matter i need like a full tf2 hitsound menu. and i tested it using mmod already anyway

Okay but give me a reason to do it tho fr
What situation would it be useful in..??

"i could do it easily but i wont"

ok.

i don't really see the point..?

but are you adding rndwave

I think it does that for a few other weapons, in general hitting several targets makes it loud 💀 I think it’s kind of a good indicator that you hit stuff but like… yeah, it’s loud.
Also this happens in tf2 sometimes as well I believe..? Mostly in MvM??
