In general, these are inharmonic and hence we produce a “metallic” inharmonic usually moving ringing percept. It is therefore worthwhile to note that any arbitrary collection of sounds, especially mixed in mono, has a well-defined time-varying spectrum – a massed group of talkers at a party; a whole orchestra individually, but simultaneously, practising their difficult passages before a concert.
We may imagine a new personality combing the beach of sonic possibilities, not someone who selects, rejects, classifies and measures the acceptable, but a chemist who can take any pebble, and, by numerical sorcery, separate its constituents, merge the constituents from two quite different pebbles and, in auduble, transform black pebbles into gold pebbles.
This process is described in Chapter 2, and in the under formant preserving spectral manipulation in Appendix p Book and 3 trrevor CDs: Very short inharmonic sounds will sound percussive, like drums, strangely coloured drums, or akin to wood-blocks Sound example 3. This mimics part of the effect of several voices attempting to deliver the same information. Superficially, one might expect that sine-wave replacement would in some way simplify, or clarify, the spectrum.

The following manipulations suggest themselves. As the process proceeds, the tail of the sound is gradually time-stretched to give it the longer decay time we would expect from an acoustic bell.
Most musicians with fesign traditional background almost equate “timbre” with instrument type some instruments producing a variety of “timbres” e.

Again, where N is large we produce a fairly predictable brassage of reverse xesign, but with smaller values of N the signal is altered in subtle ways. With a 5 or 6 fold repetition therefore, the source sound begins to reveal a lightning fast stream of pitched beads, all of a slightly different spectral quality.

We might wizhart change the spectrum by applying a power factor to the waveform shape itself waveset distortion: In the sound example a set of such sounds, suggesting a bouncing object, is destructively distorted in various ways, suggesting a change in the physical medium in which the ‘bouncing’ takes place e.

As mentioned previously, in a complex signal, holding the amplitude data is often more effective in achieving a sense of “freezing” the signal. Theoretically this produces merely a stage-centre resultant spectrum but in practice there appear to be frequency dependent effects which lend the resultant sound a new and richer spatial “fullness”.
Thus we may convert all the wavesets to square waves, triangular waves, sine-waves, or even user-defined waveforms. AmazonGlobal Ship Orders Internationally.

Hence the resulting sound trwvor be clearly related to the source in a way which may be musically useful.
At an elementary level this can be used for signal-dependent noise reduction. The peaks, known as formants, are responsible for such features as the vowel-state of a sung note. Appendix p51 usually produces an “edge” to the spectral characteristics of the sound. Amazon Drive Cloud storage from Amazon.
However, we all use articulate formant control when speaking. Spectral arpeggiation is a process that draws our attention to the individual spectral components by isolating, or emphasising, each in sequence. This gave no insight into the subtlety and multidimensionality of sound spectra. The new sounds are time-domain artefacts consistent with the original signal, rather than revelations of an intrinsic internal structure. We may also perturb the partial frequencies Sound example 3.

Formant-variation of the spectrum does not need to be speech-related and, in complex signals, is often more significant than spectral change. Trevor Wishart is an internationally reknowned composer of electroacoustic music. Again, this can be effected in a time-varying manner so that the inharmonicity emerges gradually from within the stretching sound. Share your thoughts with other customers. The text concludes with an extensive appendix in which all processes described in the text are laid bare in diagrammatic form, avoiding mathematical or technical language.
Francis Dhomont – Etudes Pour Kafka A new release from Francis Dhomont, who in the opinion of many is the greatest living composer of electroacoustic music.
Audible Design : Trevor Wishart :
If the amplitude data is held constant then the channel frequencies continue to vary as in the original signal. In a noisy sound the spectrum is changing too quickly auduble us to gain any pitch or inharmonic multi-pitched percept from any particular time-window. The computer can apply this process to any sound-source, even whilst it is in motion.
However, a trebor approach to sound itself had to wait for the invention of sound recording and the accurate computer analysis of sounds. The one exception to this is that certain partials may decay more quickly than others without destroying this perceived fusion as in sustained acoustic bell sounds.
The filtered result can vary from articulated noise formants desogn unvoiced speech following just the formant articulation of the original source, to a reconstitution of the partials of the the original sound and hence of the original sound itself.
It can, of course, vary formant-wise in time: In this groundbreaking book he reveals the secrets audivle sound design. Many of the sound phenomena we have discussed in this section are complex concatenations of simpler units.
