“Code Aptitude” meditates on the relationship between periodicity and intentionality through the filter of sonic materiality. Its form emerges from the recorded sounds of a cricket chirping arranged in counterpoint with those of a telegraph signaling. This preexistent material is transformed by means of techniques derived immanently from the analog audio devices that transduce it, as well as digital effects of pitch and duration. The resulting imbrication of concrete signals is then ornamented with a synthesized drone characterized by changing ratios that mirror those of the digital effects. By educing perceptual affinities obtaining between sounds coded alternately as “artificial” and “natural,” the periodic qualities common to both come to the fore. These ideally challenge in turn the habitual categorization of some sounds under the umbrella of intentionality to the exclusion of others of like morphology.
