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.
