Engine sounds exported from FL Studio sounds worse in BeamNG

For some reason I can't get the engine sounds in BeamNG to sound like how they were exported from FL Studio and I'm using 233 sound samples in increments of 25 rpm between 700 and 6500 rpm... I know the FL Studio sound is not the best thing in the world but I just want to know why it sounds worse in BeamNG and how to make it sound like the original FL Studio project sound.

What it should sound like:


Sound in FL Studio


Sound in BeamNG

 

I don't hear any difference here tbh

 

To me when I listen with speakers I don't hear much of a difference but with headphones there seems to be a difference. The sound in BeamNG to me just sounds like it was recorded using a low quality microphone or something and it's missing some details like with the higher frequency sounds being omitted (I'm no audio engineer expert so I don't know the proper terminology)

 

Maybe you are using some sort of low quality file format?

 

I'm exporting to WAV file format so that shouldn't be an issue. Although I see that in the audio.zip file in the folder BeamNG.drive\content, the engine sound samples that I can't play since they are password protected are pretty big sized files (20-200 KB) considering they are in the FLAC compressed file format. Does the length of the sound samples or bitrate matter and could you please provide other information I need to know about creating sound samples for BeamNG, thanks.

 

Wait, so you can see the stuff in the hidden folder but not play it? I can't even see it myself lol, I'm curious what it looks like

 

In-game, we post-process the raw engine sound in various ways, for example based on how the camera is away you are from the source. With increasing distance, the sound does not only get quieter, but also the high frequencies get gradually reduced, and the reduction already starts at very short distances. This approach is much closer to reality than simply reducing the volume. We also apply a filter based on the angle between sound source (in this case the engine) and camera, again slightly reducing the high frequencies. These are the key reasons why the sound in the second video is more muffled compared to the raw engine sounds in the FL project. We also apply reverb as part of the post-processing, which again slightly changes the sound. Another reason could be re-sampling https://en.wikipedia.org/wiki/Sample-rate_conversion

 

Wow, that's complex. Another thing I had no idea about in terms of sounds. This game's sound system is underrated.

 

There is also a static low pass filter (an eq which lowers the volume of any frequency above the set frequency of the filter) in place on the bonnet in preparation for the ability to detect when a bonnet hood has been removed. When we (as in sound recordists) record vehicle engine sounds, if this is done on a rolling road the hood is traditionally open to allow a direct path from the source of the sound to the microphone. If recording on track, the hood is of course closed, and the source sound (the engine) is close mic'd - so the microphones are set up inside the engine bay..... either way, this low pass filter will affect any sound set to be an engine sound, and remove the high frequencies.

 

I don't see all of them this way, only the old legacy engine sounds and some extras

 

I only see the legacy sounds there. No modern engine sounds that are separated between engine and exhaust.

 

I told you, these sounds are deprecated but still usable, might have been used up ontil 2017 in vanilla cars, you can find in one of the recent update changelogs that they were brought back because mods relied on them, current sounds are hidden, idk where.

 

I think the current sounds are located in the gameengine.zip file under art/sound/fmod/desktop in one of the .bank files.

 

The depreciated sounds are included in our releases to try an maintain backwards compatibility for older mods.
