Hi all, just recently got back into Train Simulator and because I'm on Windows 10, I'm using Open Rails to enjoy my content. I recently was swapping in horn sounds into the SLI Southwest Chief P40s and ran into a small problem. The horn crackles and becomes "choppy" over prolonged blasts, longer than 1 second or so. Short blasts do not create this issue. The sound file is fine when I play it in a media player so it's something on the sim side. The horn is set in the sms file to the matching 22050 frequency that the .wav was recorded at. Anyone have any ideas as to what could create this "crackle and pop"?

One of my train horns was experiencing the same problem. For me, it was the cue markers in the sound file being too close together causing the 'choppy' sound. IIRC, the horn worked fine in MSTS. In OR, i slightly lengthed the cue markers and all was well.

Did you edit it in something like Audacity or Goldwave, or is this an .sms change?

I'll try this out and report back my results so anyone else with this problem can solve it as well. Thank you!Comment

Coolhand, could you post an example of what you mean by "lengthened the cue markers ", maybe post that particular line?
Some of the horns have suddenly took a turn for the worse, choppy and squeaky in OR. They sound just great when played outside the Sim.Comment

Hi
Just to make sure its not the actual sound file (frequency, bitrate) causing this problem in OR, play the sound with the 'PlayOneShot' token and see if there is any choppy or squeaking.
If no, use the original token(StartLoop/StartLoopRelease) and then in a sound editing program, check the marker cue lines are not really close together ie example 1/3 of second or lower.
If they are not, the cue marker lines may need to be adjusted for smooth continuous playback. This can be quite tedious for perfect results.
If they are, try a larger time and then adjust for smooth playback.
As always, backup the original sound file.
I had to change only a handful of sound files to work smoother in OR. One of sound files had 15 cue markers
Never really understood why so many?
ThanksComment

Wow! This gets complicated real quick..............
I don't have such a program nor am I really interested at this stage of getting/using one. Just thought it might be just editing a line in NotePad or something. My brain is too old to start on something else new, with all the other stuff I have going on, Lionel layout reconstruction, Antique car (summer) and work.
Thank you for the clarification and if someone with talent like you, could re-do some of the more popular horn types for use in OR, Ancients such as myself would be very grateful.Comment
