Engine sounds like a vacuum cleaner

I'm getting pretty good at making seamless engine sound loops and they sound awesome until I add them to the game. Then they sound all "whoosh whoosh whoosh". A little hard to describe, but a "vacuum cleaner" is pretty similar. I guess you could say it sounds more like a jet engine than internal combustion. Any opinions on what might cause this/ how to fix it? I'm using the standard wav export that Audacity allows, 16hz, 44100 bitrate. Some guides that I've read say that should be fine.
 
Have you matched the RPM of the sound samples at the end of the .sfx file ? If not then the pitch will never match.

Yeah, there's no harsh transitions in the pitch. I found out that Audacity wasn't actually saving them as 44100 Hz. Fixed that and it sounds a little better. Also adding some distortion to the sounds makes them sound more natural somehow. Curious what other techniques people use.
 
Lets get this tread going. I have made my first attempt in sound modding yesterday, and it is quite interesting thing to do.

But I have ran into an issue, which perhaps is on the same branch, sounds not as vacuum cleaner but altered very much. At first my recorded and prepared samples were working well, and I was quite happy about them. Later same day after launching rF2 in the evening I immediately noticed that my samples aren't playing the same way anymore. They sound like if they would have got through some heavy smoothing filter, and only due few characteristic imperfections I can tell that the same samples are actually being played. This is very strange, especially as they all worked fine at start.

At first when I have got setup activation rev ranges well, the sounds were clearly as from recordings, now they have no similarity.

I am also using Audacity. .wav 44100Hz, 16bits. Tried exporting all of the sounds as mono, same issue prevails. I thought maybe it is just in devmode, but it is same in main game. Tried renaming files, no help, as if the issue is with the .wav files.
 
I have already tried to convert into mono, made no difference. And I have used all kinds of troubleshooting. Even the very early samples that are identical to those that worked for me at first, sound just as bad as any. I am almost sure that something got corrupted specifically regarding those sounds. But I have no idea what. I have not found any duplicates. I have tried fresh install of devmode.

Thats modding at its worst lol
 
Is this happening with .sfx or .json sound file? Think you could upload a clip? Is it possible that there is a sound (Like the road noise) that is overpowering everything?
 
It is with .sfx. I think I would like to get it right before trying next step (if I will even go to do new sound engine engine sound lol)

It just seems to me like if the sound samples are almost conflicting amongst themselves. I try renaming, in various ways. Nothing works.

We will see, I might upload something if I'll continue being stuck. Surely not this year, in 2025, I hope.
 
I just looked at my sounds and they are at the .wav 44100Hz, 16bits. So that shouldn't be the issue. Only thing I can think of would be to comment out sections of the .sfx and reload the game. That would try to isolate which sound would be the culprit.
 
Thank you for idea. After trying it does seem like they all just simply are bad files for whatever reason. If I replace the sounds with others, then they are fine. Just all audio files that I created are bad, and I can not think of any reason why. I would not be trying to solve anything if they wouldn't have been perfectly well working at first, and I can't think of any reason what could have happened.

Anyway, new years in my place will be in three hours and twelve minutes.

I guess will continue this next year. Happy New Year everyone :)
