- The amplification value determines the scaling factor by
- which the amplitude of the audio stream is multiplied. The
- formula for the scaling factor is
-
- factor = 1 + amp / 64.
-
- For example, an amplifiction value of zero results in a
- scaling factor of one while an amplification value of 64
- means to double the volume.
