When transforming the harmonicity of the spectrum, we run into problems about the position of formants akin to those encountered when pitch-changing see Chapter 2 and to preserve aishart formant characteristics of the source we need to preserve the spectral contour of the source and apply it to the resulting spectrum see formant preserving spectral manipulation: However, we all use articulate formant control when speaking.
If the partials are not in this relationship, and provided the relationships from window to window remain relatively stable, the ear’s attempts to extract harmonicity whole number relationships amongst the partials will result in our hearing several pitches in the sound.
In particular, put forward the ideas of sound landscape handling sound images and representation using soundand sound transformation eishart a unifying principle for composing, traditionally or with sounds.
Finally, we may shuffle the time-window data in any way we choose spectral shufflingshuffling windows in groups of 1 or 2 or aucible etc.
This CD contains 3 studies which were the seeds from which many of his other works grew. Because most conventional acoustic instruments have no articulate time-varying control over spectral contour one of the few examples is hand manipulable brass mutesthe concept of formant control is trevr familiar as a musical concept to traditional composers.
The following manipulations suggest themselves. As this process destroys the original form of the wave I will refer to it as destructive distortion. 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”. These shade off into the area of “Texture” which we will discuss in Chapter 8.
Spectral thinking is integral to all sound composition and should be borne in mind as we proceed to explore other aspects of this world. We may also perturb the partial frequencies Sound example 3.
This is quite a complex task which will involve pitch tracking and pattern-matching to estimate where the partials might lie on a window by window basis.
Most of these are only interesting if we apply them to moving spectra because they rely on the interaction of data in different time windows – and if these sets of data are very similar we will perceive no change.

Again, this can be effected in deisgn time-varying manner so that the inharmonicity emerges gradually from within the stretching sound.
The book Audible Design wixhart, provides detailed description of the craft of sound transformation using new sudible instruments, with non-mathematical explanations and recorded music examples of all processes.

Two processes are worth mentioning in this respect. Get fast, free shipping with Amazon Prime. As the digital signal will retain its duration precisely, all the components in the shifted signal will line up audibel with their non-shifted sources and the spectrum will be thickened while retaining its fused integrity.

With a complex waveform, it enriches the spectrum in a not wholly predictable way, though we can fairly well predict how the spectral energy will be redistributed. The most important feature to note is that all sound spectra of musical interest are time-varying, either in micro-articulation or large-scale motion. Finally, we may introduce small, random changes to the waveset lengths in the signal waveset shaking: Bearing in mind that these do not necessarily correspond to true wavecycles, even in relatively simple signals, we will anticipate producing various unexpected artefacts in complex sounds.

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. Such distortion procedures work particularly well with short sounds having distinctive loudness trajectories. If you don’t know his music, we recommend that you make an acqaintence with it by listening to some clips and reading the comprehensive notes which we have on the site.

I wrote to several friends asking them to collect voices from their local radio stations, and also recorded voices from TV stations via satellite dish, assembling sounds from voices in 26 different languages. Denis Smalley is one of the UK’s best known composers of electroacoustic music, and this CD is a personal favourite of ours – definitely a desert island disc.

Again, where N is large we produce a fairly predictable brassage of deeign segments, but with smaller values of N the signal is altered in subtle ways.

L’Oeuvre Musicale The complete works of Pierre Schaefferre-digitised and re-issued with newly discovered tracks. Spectral time-stretching, which we will deal trebor more fully in Chapter 11, can produce unexpected yrevor consequences when applied to noisy sounds. We may imagine a new personality combing the beach of sonic possibilities, not someone deign 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 fact, transform black pebbles into gold pebbles.
This can be achieved purely vocally over a drone pitch by using appropriate vowel formants to emphasise partials above the fundamental. This is why we can produce coherent speech while singing or whispering.
By making wjshart what was not previously perceptible we effect a “magical” transformation of the sonic material. Amazon Restaurants Food delivery from local restaurants.

This means that the partials are moved upwards in such a way that their whole number relationships auvible preserved less and less exactly and eventually lost. For example, every alternate waveset may be replaced by silence. A good example of the complexity of noise itself is “noisy noise”, the type of crackling signal one gets from very poor radio reception tuned to no particular station, from masses of broad-band click-like sounds either in regular layers – cicadas – or irregular – masses of breaking twigs or pebbles falling onto tiles – or semi-regular – the gritty vocal sounds produced by water between the tongue and palate in e.
