+       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.
