Electronically Generated Sound Effects
Synthesized Sound Effects
a synthesizer is an audio instrument that uses sound generators to create waveforms
Computer-Generated Sound Effects
difference between a synthesizer is that the synthesizer is specifically designed to create and produce sounds, the computer is not
with appropriate software, the computer can work like the synthesizer
can store programmed sounds, create them from scratch, or both
computer programs make it possible to call up a particular effect and also to see and manipulate its waveform and therefore its sonic characteristics
Sampling
a process whereby digital audio data representing a sonic event, acoustic or electroacoustic, are stored on a disk or into electronic memory
the samples can be of any length, as brief as a drumbeat or as long as the available memory allows
a "sampler" is a specialized digital record and playback device
a "sequencer" is an electronic device that stores messages, maintains time relationships among them, and transmits the message where they are called for from devices connected to it
sampling system allows us to produce an almost infinite variety of sound effects by shortening, lengthening, rearranging, looping, and signal-processing the stored samples
The Samplefile
after a sample is recorded or produced, it is saved to a storage medium (referred to as samplefile)
can be easily distributed
Design Sound Effects
designed effects are created after recording and during editing
the waveform of the recorded effect is reworked by changing its pitch, dynamics, timing, and envelope
