Book and 3 x CDs: We may vary this spectral stretching process by changing the overall stretch i. Spectral fission can be achieved in a number of quite different ways in the frequency domain. We reach the area of noise see below.

With dense or complex spectra the results deeign filtering can be relatively unexpected revealing aspects of the sound material not previously appreciated. Ideally it must deal in some way with inharmonic sounds where the form of the spectrum is not known in advance and noise sources where there are, in effect, no partials.

We can use spectral freezing to freeze certain aspects of the spectrum at a particular moment. The wushart important feature to note is that all sound spectra of musical interest are time-varying, either in micro-articulation or large-scale motion. This mimics part of the effect of several voices attempting to deliver the same information. Trevor Wishart is an internationally reknowned composer of electroacoustic music.


More radically, sets of narrow band pass filters can be used to force a complex spectrum onto any desired Hpitch set HArmonic field in the traditional sense. Values of N at the threshold of grain perceptibility are especially interesting. Many of these processes e.

The opposite process, whereby the spectral components seem to split apart, we will describe as spectral fission. Inverting the half-wave-cycles waveset inversion: Book Details for Trevor Wishart: Vocoding hence works well on noisy sounds e.

Spectral arpeggiation is a process that draws our attention to the individual spectral components by isolating, or emphasising, each in sequence. For this reason I refer to these processes as constructive distortion.

It merely contributes to the more general percept of noisiness. By searching for wavesets zero-crossing pairs: Would you like to tell us about a lower price? We may average the waveset shape over N wavesets waveset averaging.

Note that, small stretches produce an ambiguous area in which the original sound appears ” coloured” in some way rather than genuinely multi-pitched. Get to Know Us.

It is also possible to normalise the spectrum before imposing the new contour. In the 19th century, european composers became increasingly concerned with ‘sonority’, through development of new orchestration techniques, and new instruments.

This can be achieved purely vocally over a drone pitch by using appropriate vowel formants to emphasise partials above the fundamental. East Dane Designer Men’s Fashion.

Welcome – if you are a returning customer, log-on to your account. With a complex waveform, it enriches the spectrum in a not treor predictable way, though we can fairly well predict how the spectral energy will be redistributed. As we know from singing, and as we can deduce from this diagram, the frequencies of the partials in the spectrum determining pitch esharmonicity-inharmonicity, noisiness and the position of the spectral peaks, can be varied independently of each other.

In a very simple sound source e.
