音色和情感是音乐声音最重要的两个方面。两者都是复杂的、多维的，而且密切相关。以前的研究已经确定了许多不同的音色属性，并表明光谱质心和攻击时间是音色的两个最重要的维度。然而，关于其他方面的共识尚未出现。这项研究将试图识别光谱质心和攻击时间之后最具知觉相关性的时间属性。要做到这一点，我们将考虑各种持续的乐器音调，其中频谱质心和攻击时间已经相等。虽然之前的大多数音色研究都使用辨别和差异测试来理解音色，但研究人员最近开始使用情绪测试。以前的研究表明，攻击和光谱质心在情绪知觉中起着至关重要的作用，它们可以如此强烈，以至于听者不太注意其他光谱特征。因此，在本文中，为了分离第三个最重要的音色特征，我们设计了一个主观听力测试，使用情绪反应对攻击、衰减和频谱质心均衡的音调进行测试。结果表明，偶/奇次谐波比是攻击时间和频谱质心后最显著的时间特征。
Timbre and emotion are two of the most important aspects of musical sounds. Both are complex and multidimensional, and strongly interrelated. Previous research has identified many different timbral attributes, and shown that spectral centroid and attack time are the two most important dimensions of timbre. However, a consensus has not emerged about other dimensions. This study will attempt to identify the most perceptually relevant timbral attributes after spectral centroid and attack time. To do this, we will consider various sustained musical instrument tones where spectral centroid and attack time have been equalized. While most previous timbre studies have used discrimination and dissimilarity tests to understand timbre, researchers have begun using emotion tests recently. Previous studies have shown that attack and spectral centroid play an essential role in emotion perception, and they can be so strong that listeners do not notice other spectral features very much. Therefore, in this paper, to isolate the third most important timbre feature, we designed a subjective listening test using emotion responses for tones equalized in attack, decay, and spectral centroid. The results showed that the even/odd harmonic ratio is the most salient timbral feature after attack time and spectral centroid.
