Next we analyze the influence of the number of sounds that are played at
one time. The result is shown in Figure 8.9, where the horizontal and vertical
axes denote the number of simultaneous sounds and the average of errors,
respectively. The average error becomes gradually higher as the number of
simultaneous sounds increases and those two error patterns look similar.
