(A composition, Sound Installation and Space Intervention, using Modal Filters and Convolution)
Spoken words carrying a secret are usually whispered ear to ear. Secrets are messages carrying sounds which conform groups of syllables with few pitched sounds but revealing signals with a filtered noise characteristic. Consonants in such whispered words are bare noticeable framed only by nuances and shades of sounds which bound meaning in a bis-a-bis context. Sound intensity in spoken secrets is reduced to a minimum thus avoiding eavesdropping for there is an agreement between emitter and receiver in message transmission. Sounds in secrets carry information that on makes sense depending on context, narrative and listener prejudice.
Given the above ``Chuchoter'' is framed under the assumption that its sounds have ``whispering'' quality. This material has been rendered using signal processing techniques such as spectral convolution as well as ``HiQ Two Integrator'' filtering techniques developed by Max Mathews and the composer. Conventional convolution between pitched sound signals and spoken words was used to obtain one of the sets of sounds for this composition. The other set was achieved using above mentioned filters on long sounds with wide spectra.
Although in design ``Chuchoter'' is a sound installation, this composition avoids the notion of instant gratification demanding time and duration on its perception plus a multi channel, multi source sound context space for its difussion. Because of its sound/space intervention features, sound sources travel a path inside a boxed environment obtained by intensity panning on each audio signal. This piece was composed using Common Lisp Music (CLM), on a PlanetCCRMA Linux workstation. Thanks to Daniel Cahn-Speyer for providing sound sources for this composition.
