Flangey Engine Sounds...?

[Smileyman]

Here's an interesting one.

I've downloaded a load of BR Class 158s from the DLS, and I noticed that some of them have a 'Flange' or phasing quality to the engine sound, and at higher speeds it's really pronounced.
(I swear, Deadmau5 would be proud of that flange!)

While I really enjoy Deadmau5 using flange (phasing) the way he does, it's not what I want to hear coming from a train.
If you don't know what I mean, download the Arriva 158s and have a listen. It's not subtle!
Even changing the engine sounds to a different asset doesn't stop it happening.
I changed the Arriva one to use the engine sounds from the DMU 101, but as soon as it got up to speed...Bwwooooiiiinnnnnn)

Is it something in the Engine Spec file that's doing this?
I haven't got around to checking that yet by changing it out, so thought I'd ask here first.

Anyone else experience this?

There used to be a lot of very knowledgeable people on Trainz engine spec files and engine sound files in this community back in the day.
I know some had left before I took my break from Trainz, but I don't know how many are still here.

I was hoping that someone would have some info on the 'flange' effect that I'm getting.
I know it's not the sound files themselves, as the example I mentioned above proves, so it does seem to point to the engine spec file.
Has no-one else experienced this?

I don't really want to change the engine spec file, as you then have loco performing NOT like they're supposed to.
I think I might change the one mentioned in the first post, and see if that fixes it, so we at least know it is the engine spec file that's causing it.

If it turns out not to be the engine file, then I have no idea what it could be.

Well, I've tried everything (except changing the build number from 3.5 to 5.0, but that shouldn't make a difference. Maybe I'll try it later).

No idea why they wouldn't sound exactly the same with both the same Engine Sound Asset and the same Engine Spec Asset.

Before I give up, and just put up with the ridiculous sound (or stop using that train), I thought I'd record what it is I'm talking about.

Very first ask Yourself: Did I provide really sufficient info for others to test both good/wrong DMUs in their version of the game?

Which Arriva 158 is it as there are several on the DLS. Do you have the kuid?

Edit: never mind, I think I have it as the rest are 153s.

I think it may just be the sound files and the way they mesh together that make that throbbing sound. I personally think it sounds alright although I'll be the first to admit that 158s aren't my usual interest so I'm not the best person to comment on whether it's 'correct'. If it helps, I tested it in Trainz+ build 132284.

I noted that the speedometer begins at 80 odd though so by 13mph I was doing 100mph...

But that's the thing.
The video I posted shows the modern (only made a few years ago I believe) 101 DMU and the old 158 running, but they both use the same sound pack (asset) for the engine sounds, and they both use the same engine spec asset, (I changed the assets the 158 uses to match the 101 DMU to so I didn't have to listen to the flange) so in theory, they should both sound the same.

The only difference between the two is the shell that we see.
Unless there's something else that affects the sound of the engine when making a loco in Trainz, I don't know.
That was the purpose of my thread.

Strange about the speedometer though.
It is a very old model, but still.

As for which 158, well there are a load of them on the DLS, and I think most if not all of them are reskins of one, but I haven't tested the others yet to see if they behave the same.

In the video above, they don't sound anything like each other, so there must be something else in the makeup of the loco that affects sound.
Beats me what it could be.

But thanks for taking the time to have a look.
Appreciate it.
