New old-casting P3—comments, please

[SP9800]

Here's a new recording of an old-casting AirChime P3. It's from the Oakland Terminal Railway's GP7U, but it'll go great on your SP units. I did the looping with GoldWave, and IMO it sounds pretty good.

Download this .zip only if you feel confident that you can figure out how to use the files, either by renaming them or editing the .sms file. As a sort of beta, I don't really feel like adding documentation.

Tell me what you think of it, please.

See Here,
Im using Goldwave too and I almost tossed the whole cpu out the window. I have about 10 recordings im tryin to make a horn with. Well a horn for each recording. How'd you go about doing it. I can get the start and finish cue points but thats it
Could you e-mail me and tell me your procedures. I would appreciate it. My e-mail is Firegreen@seark.com

First of all, you want to set up Goldwave to loop the selected portion of the sound. First open the Device Controls Properties:

Then set it to loop the selection portion as many times as it can:

This sets it so that the User Play (smiley face next to a green right arrow) button plays the selected portion of the sound over and over again.

When you open a brand-new recording to start work on it, make sure you resample it to 11,025 Hz first. Then, set the start marker (left-click on the waveform graphic) at the very beginning of the file and place a cue point there. This is to comply with the MSTS cue point numbering convention. You will delete it later.

Next, you want to move the start (left-click) and finish (right-click) markers around on the waveform to a point where it looks approximately the same volume and wave pattern. Then click the User Play (smiley/arrow) button to loop that part of the sound over and over, just like MSTS would do. If it doesn't loop smoothly, move the markers a little and press the button again. If it begins to sound like it's looping pretty good, but not quite perfect, zoom in (Shift + up arrow on the main GoldWave window) on the waveform until it looks squarish:

You can now move the markers around sample-by-sample until it sounds good. Note that this process can take a LONG time! When it sounds good, DO NOT move the markers until you have placed cue points as follows.

When it finally sounds good, go to the Tools menu and click Cue points. Enter a name for the first one (I just enter a number), set it to "Start marker," and click Add. Add a second cue point by entering another number for the name, set it to "Finish marker" this time, and again click Add. You now have the two necessary cue points for looping in MSTS. You can now select that very first cue point you added at the beginning and click Delete to remove it.

Now you can save your file. For the in-cab file, set the "File Attributes" to "16 bit, stereo, signed." For the external sound, set that to "16 bit, mono, signed." To follow convention, use the same filename for both files, except add "x_" to the external file.
