--
  v2: dsound: Premultiply the input value by firgain and the interpolation weights in downsample.
      dsound: Transpose the FIR array to make the element access sequential.
      dsound: Calculate firgain more accurately.
      dsound: Swap around the two nested loops in downsample.
      dsound: Calculate required_input more accurately.
