Tutorial 6A review of fundamentalsSolution to Exercise 3Finally, we need to use one more amplitude envelope to create a global diminuendo. Thetwo tones go to yet another *~ object, controlled by another line~. As noted earlier, astraight line decrease in amplitude will not give the perception of constant diminuendo inloudness.Therefore, we used five line segments to simulate a curve that decreases by half every twoseconds.100 10 sec.Global amplitude envelope decreasing by half every two secondsThis global amplitude envelope is inserted in the signal network to scale both tones downsmoothly by a factor of .03125 over 10 seconds.Both tones are scaled by the same global envelope98
