The parameters of the sound's envelope (attack, decay, sustain and release) are manipulated to change its sound. In this case, the decay is vastly increased, sustain is reduced, and the release shortened. The resulting sound is audible for half as long as the source sound: 613: 716: 670: 423: 377: 480: 556: 317: 257: 120:, subtractive synthesis was the nearly universal electronic method of sound production. Its popularity was due largely to its relative simplicity. Subtractive synthesis was so prevalent in 611: 714: 668: 421: 375: 478: 554: 315: 255: 612: 715: 669: 422: 376: 479: 555: 316: 256: 27: 447:
The pulse-width modulated sounds are now combined at equal volume. Combining them at different volumes would create different timbres. The result is a 2-second

Subtractive synthesis has become a catchall for a method where source sounds are modulated, and it is sometimes applied inappropriately.
