This method converts a raw wave value (range: -1 to 1) to actual decibels. Decibels are measured using an exponential scale. -100dB is total silence. -60dB is usually the noise floor. When the signal reaches or goes past 0.0dB it is considered distortioning. The decibel range returned is -100dB to 10dB.
