By default, when the input channel delay, α, is set to zero, the data throughput delay (T) is: T = 2 frames + (n - m).
Assuming that m (input channel) and n (output channel) are equal, we have the figure below, in which the delay
between the input data being written and the output data being read is exactly 2 frames.
Assuming that n (output channel) is greater than m (input channel), we have the figure below, in which the delay
time between the input channel being written and the output channel being read exceeds 2 frames.
Assuming that n (output channel) is less than m (input channel), we have the figure below, in which the delay time
between the input channel being written and the output channel being read is less than 2 frames.
