I would like to know why on some locomotives when you throttle up the transition of sound is not good. In other words the sound will fade away and before the next sound will start. There are moments when I throttle up or down on a diesel when the sound disappears altogether for a moment. On other locomotives with the same sound (in my case GP38) the throttle up and down works properly with the sound.

It has to do with the way the sound files are set up in the first place....looping, etc. I'm not sure how to do it myself -- I have tried using sound altering programs such as GoldWave, but with no success.One of the worst engine sound files for the unsynchronized throttling up/down sound matching seems to be the Fairbanks-Morse. Maybe it's just my system, but I really have to turn the volume down if I run the FM as the engine sound is so loud inside or outside of the cab. The sounds are quite correct, rode on or behind many FM locos; it's just the volume and the transition from one throttle setting to the next that seem to be way off.

A lot of it has to do with the structure of the SMS files and the number of wave files used. I wrote some SMS files for some engine sounds, with recordings for all eight different engine settings. I ended up having to use four different streams in order to make sure a stream had time to finish playing before it had to play another sound. Even so, I still occasionally hit dead spots.

Thanks.
Do the bit rates have anything to do with it. For example why is there one rate for inside the cab and another for outside the cab.??

The sounds for the inside and the outside both use the same bit rate. However, the inside sounds are stereo, while the outside sounds are mono.For what it's worth, the problem occurs both inside and outside.
