In this study, we produce a geometrically scaled perceptual timbre space from dissimilarity ratings of subtractive synthesized sounds and correlate the resulting dimensions with a set of acoustic descriptors. We curate a set of 15 sounds, produced by a synthesis model that uses varying source waveforms, frequency modulation (FM) and a lowpass filter with an enveloped cutoff frequency. Pairwise dissimilarity ratings were collected within an online browser-based experiment. We hypothesized that a varied waveform input source and enveloped filter would act as the main vehicles for timbral variation, providing novel acoustic correlates for the perception of synthesized timbres.

减法合成器的音色空间表示

在这项研究中，我们从减法合成声音的不同等级产生几何缩放的感知音色空间，并将结果维度与一组声学描述符相关联。我们策划了一组 15 种声音，这些声音由合成模型产生，该模型使用不同的源波形、频率调制 (FM) 和具有包络截止频率的低通滤波器。在基于浏览器的在线实验中收集成对差异评级。我们假设变化的波形输入源和包络滤波器将作为音色变化的主要载体，为合成音色的感知提供新的声学关联。
