Was wondering if anyone else has come across this issue and if so, how do you fix it?

When I create a sound inside of Sony's Sound Forge and then load it into my engine it seems that Sound Forge has a greater range of volume, pitch, and frequency than my engine.

For insance I created a very low-pitch engine loop that is played when you are moving around in 3D space with your ship. But it cuts out inside of the engine as if it is clipping on the low side of the spectrum.

The engine is setup for 44100 hz sound with stereo mixing so I'm not sure what is going on.

Any ideas on how I might fix this?
