SoundSketcher research
Listening experiments and interface reconstructions that shaped SoundSketcher’s mappings, examples, and evaluation logic.
A bilingual showcase of the sinusoidal matching task used to study pitch-height judgements for non-harmonic, noisy, and acoustically ambiguous sounds.
Research question: when a sound lacks a stable fundamental frequency, can listeners still make reliable pitch-height matches?
A reconstruction of the questionnaire interface used to collect preferences for visualizing mixtures between noisy and tonal components.
Research question: how should SoundSketcher represent sounds that sit between textural noise and stable tonal material?
The indefinite-pitch showcase is backed by the JASA Express Letters paper Beyond fundamental frequency: Pitch height judgments in Indefinite-Pitch sounds by Konstantinos Velenis, Asteris Zacharakis, and Emilios Cambouropoulos. The noise-tonal page presents study materials and exploratory analysis for a related SoundSketcher questionnaire workflow.
