The musical passage is likely to sound artiﬁcial, because it is created from pure sinusoids. You can improve the quality of the sound by multiplying each pure tone signal by an envelope E(t) so that it would fade in and out. x(t) = E(t)cos(2ˇf 0t+ ) small black kitchen tables

"WebThe right-hand column shows the spectrum of the sound - how much of each sine-wave you have to add together in order to make that particular waveform. The upper panel is a sine wave tone with a frequency of 1000 Hz. A sine wave has energy at just one frequency, so the spectrum is just one point. waveform -----spectrum " - Each sound is just made from sinusoids
