Tiger Trains MTA set Horn Sound

[Don6218]

Hello, I am having an issue with the horns contained in the new MTA set from Tiger Trains.

All the sounds including the bell sound great and proper. The horn on the CabCar sounds like crap. It is hard to describe but it is VERY high pitched and Warbbles! Instead of a good long or short blast it just stutters.

Now, I have substituted a couple of other horns, they sound great just playing them from the source folder and from other locomotives, but when inserted into the CabCar Cab-Sound folder they also sound very high pitched and some stutter. After watching some You Tube videos containing Cab Car horns, the real ones do not stutter, thought it might be someone's idea for a more noticeable sound.

Any ideas before I modify the Cab Sounds folder further? The external sound is normal sounding, only the internal cab sound is screwy!

Like I said, all the other sounds are fantastic, at a reasonable level and very realistic. This is the first time I have run into this.

Don, aren't the MTA engs in the set aliased to sounds that are installed by default in the Common.Snd folder?

Look in the engine file you are having difficulties with at these two lines: (these are from TTMTACC6111.eng )
Sound ( "..\\..\\Common.Snd\\TT_NJTComet\\NJTcometEng1.sms " )
Sound ( "..\\..\\Common.Snd\\TT_NJTComet\\NJTcometCab1.sms " ) >>> this is the one controlling the interior cab sounds

Please post these lines from your file.

Yes those are the lines, when I go to "Common Sounds" and select the "MTAhornINT or INT2 orINTa (original)" they sound proper.

It is within the game that it sounds stuttery and high pitched. I tried the same sounds with the NJT "Comet" cabcar and it sounds proper. I believe there may be an issue with something within the MTA Eng/Int folders that may be the problem, or something OR is not reading correctly. It is a strange conundrum!

It sounds like it's just the horn, right?

If so, it's possible that the sound file is at the wrong frequency compared to the rest, in which case you have two options:
1- either change the frequency curve to match the sound or add one if it's necessary, or
2- change the sound file to the right frequency, most likely by resampling to the right frequency (to my knowledge, only Goldwave can edit sound files without removing the looping cuepoints)

There is also the possibility that the interior sound is mono instead of stereo, as interior sounds need to be. The only way to fix it would be to open it in Goldwave and resave it as a stereo file.

I just swapped out MTAhornINT.wav for K3L22k.wav and it sounds fine. MTAhornINT.wav is a small file (48kb)...one short burst of the horn, that's all. K3L22k.wav sounds fine in the cab. I subbed in the exterior horn MTAhornEXT.wav and it sounds bad.

It appears the sms file is playing repeated quick bursts of the horn which then sounds like it is stuttering.

Not know much about sound files or the ORTS sound code, I cannot tell if the problem is within the sound file (as Travis suggested ) or ORTS.

I am going to swap out the whole file as you have it in your post, I see that a couple of the numbers are different, I don't have that program to modify the frequencies.

Yes, I did notice that it is only a very short duration for the OEM TT horn blast.

Well thank you all for the suggestions, we'll see what happens.
