A priory, there is no difference between "sound" and "noise" unless you have aditional information.

• Are you looking for a lowpass filter to remove high frequency noise?
• Do you have single outliers (crack, snapple and pop) that you want to remove?
• Do you have 50Hz line noise (hum) to remove?
• ??
