Exploring the relation between fundamental frequency and spectral envelope in the perception of musical instrument sounds – sound files and participant responses

This database contains synthesized instrument sounds (sounds.zip), participant responses (data.zip), and a key for the stimulus order (stimKey.zip) as complementary data to [1]. Sounds include individual stimuli for two experiments. Experiment 1 contains stimuli used for sound pleasantness and sound brightness ratings. Every rating scale includes three acoustic conditions: congruent, incongruent, and fixed, corresponding to the relation of fundamental frequency (F0) and spectral envelope (SE). See [1] for further details on this matter. Experiment 2 contains stimuli for four synthesized instrument sounds: violin, alto voice, clarinet, and tuba. Sounds were synthesized using congruent spectral envelopes (all), and register fixed spectral envelopes (low, mid, high). All sounds are mono signals with a sampling frequency of 44100 Hz in WAV format. Data includes four sets of participant response data: sound pleasantness ratings (Exp. 1), sound brightness ratings (Exp. 1), sound pleasantness ratings (Exp. 2), and sound plausibility ratings (Exp. 2). StimKey provides values for the first and second principal components of the synthesis space for the pleasantness (1 to 81) and brightness (1 to 16) stimulus numbers for Exp. 1. Names convention for Exp. 2 sounds: InstrumentName_congruencyCondition_F0..wav References: [1] Work in progress

本数据库包含作为文献[1]补充数据的合成乐器声音（sounds.zip）、被试反应数据（data.zip）以及刺激顺序密钥（stimKey.zip）。声音包含两项实验所用的独立刺激材料。实验1的刺激用于声音愉悦度与声音明亮度评分任务，所有评分量表均涵盖三种声学条件：一致、不一致与固定，分别对应基频（fundamental frequency, F0）与频谱包络（spectral envelope, SE）的对应关系。相关细节可参阅文献[1]。实验2包含四种合成乐器声音的刺激材料：小提琴、女中音、单簧管与大号。所有声音均采用一致频谱包络（全部）与音域固定频谱包络（低、中、高）合成。所有声音均为单声道信号，采样率为44100 Hz，格式为WAV。数据集包含四组被试反应数据：实验1的声音愉悦度评分、实验1的声音明亮度评分、实验2的声音愉悦度评分，以及实验2的声音合理性评分。StimKey提供了实验1中愉悦度评分（范围1至81）与明亮度评分（范围1至16）所用刺激的合成空间第一及第二主成分数值。实验2声音的命名规范为：InstrumentName_congruencyCondition_F0..wav。参考文献：[1] 正在进行的研究
