    "slowing" sounds

    Hello all. I'm working on various track sounds and I'm curious as to how to "slow" the sounds down. I'm currently working with a recording of a six-axle locomotive, recorded at about 15mph on stick rail. With how everything is set up right now, the sounds are playing at about twice the speed of the locomotive if you catch what I'm saying. What would be easiest to change to better sync up the sound with the locomotive speed, altering the .wav file, or editing the .sms file. How would I go about doing either? For reference, I'm using Goldwave v5.58 for editing sounds.

    Thanks!

    EDIT: Here's a snippet of the .sms file entry. I "borrowed" the code from a Hungarian locomotive with similar sounds added. Being a narrow-gauge locomotive, it's rather obvious as to the difference in speed between my audio file and the borrowed code.

    I don't quite see what narrow gauge has to do with it.

    You could start by modifying the frequency curve, something like:

    FrequencyCurve(
    SpeedControlled
    CurvePoints ( 3
    -30.000 22500
    0.000 4000
    30.000 22500
    )

      Narrow gauge locomotives are typically shorter in length and have a shorter wheel base and axle spacing, therefore the sound of the wheels hitting a joint in the rails would be quicker than a larger, standard gauge locomotive going at the same speed. And thank you, I'll give that a try.
