MTH Premier SD50 Blower Sound

Bob.....I have that problem with a couple of different MTH diesels, I found that if using the DCS handheld control use the Labor/Rev Up button to make the prime mover sound go to higher rev sound the scream goes away and I think the engine sound is better.

But....it's prototypical.

If you don't want blower whine in the sounds. You'll have to go with older non turbocharged diesels😉

Thanks Clem and Rick.

I’ll try the Labor Up button on my SD40, but if you have to hold the button the whole time you run it, that’s not gonna do it for me.

The problem I think is that the sound files are recorded from real size locos, but the small speakers in model trains are better at reproducing high frequencies.  Models of naturally aspirated engines all sound fine to me.  And whether the real loco has a turbocharger or supercharger does not seem to determine which models have high pitch blower sounds.  Possibly some sound files were modified to filter out high frequencies.  Possibly some were recorded when the blower was not loaded.  Some of my best sounding locos are the E8 and GP38.  The worst ones to my ear are the F7 and SD40.

The real SD50s may sound fine, but that may not translate to the model.  I don’t know.  That’s what I’m trying to find out.

I wonder if you could extract that from the sound file, run it through a low-pass filter, and reload it.

He can change the sound file and pick one he likes. If the turbo sound isn’t his cup of tea, find a N/A diesel file and load it. Of course, be wary of chain files that could affect lighting, etc. There are aftermarket sites you can play around with files that would allow you to accomplish this, and it’s not like it’s an ancient Chinese secret,…..If this is real problem for you, but you like the models, then customizing sound files is something you probably should learn to do, as just about every modern diesel locomotive is forced induction in some sort of way, ……Then you can become self sufficient, and not rely on bandaids to get you by……

Doh! I used YouTube before to find a sound file.  Not sure why I didn’t think about it for the SD50.  So far, I haven’t found one where the youtuber isn’t blowing the horn or ringing the bell when loco is running track speed.  But it sounds like the loco has a blower whine.  I’ll look more when I am done a honey do painting job.

Pat – I’m too lazy to learn how to replace sound files.  And my friendly neighborhood ASC Certified Tech is only 30 minutes from me.  John replaced the file in an F7 for me.  I picked an E8 file that sounds great but seems funny to have two diesels start up when you push the start up button.
