A Tutorial on Spectral Sound Processing Using Max/MSP and Jitter

摘要

For computer musicians, sound processing in the frequency domain is an important and widely used technique. Two particular frequency-domain tools of great importance for the composer are the phase vocoder and the sonogram. The phase vocoder, an analysis-resynthesis tool based on a sequence of overlapping short-time Fourier transforms, helps perform a variety of sound modifications, from time stretching to arbitrary control of energy distribution through frequency space. The sonogram, a graphical representation of a sound's spectrum, offers composers more readable frequency information than a time-domain waveform.
