I figure this beeping and crackling you hear are the result of wrong DC offsets.
You can counteract this problem by doing the following:
* Open the setup screen
* Go to the tab Player
* Move down to Sound Quality
* Increase the value at samples to atleast 42 but longer can be required
* If that doesn't fix it, lower the WFIR Cutoff value.
If all above doesn't work, you can try to convert the song to an .IT file by going to the general tab in your song (not setup screen), press song properties, and Choose Impulse Tracker IT. Press ok and play your song again.
