Atravessamentos

Audiovisual material from the artistic work called  Atravessamentos by Luzilei Aliel and Damián Keller (Aliel, L., Keller, D. and Alvim, V. 2019.) 

Atravessamentos makes use of ecological modelling to expand the available sonic resources while keeping close ties to everyday events. A specific contribution of this piece is the incorporation of acoustic-instrumental synthesis within the context of ecologically grounded creative practices.

Atravessamentos features sonic-generative techniques based on acoustic-instrumental sources. These emulations are produced by decoding the dynamic spectral structure of the recorded sources to recreate or emulate acoustic-instrumental sounds, consequently yielding an expansion of the instrumental palette.

Audio-processing techniques are employed to enhance the perceptual qualities of the recorded materials through timbral bridges linking the synthetic and the recorded resources. Reverberation provides distance cues that sometimes are consistent with the imagetic content and other times contradict the visual cues. 

In Atravessamentos the instrumental sounds furnish dense sonic textures, yielding dynamic clusters and glissando-based sound blocks
