目前，正弦建模通常包括正弦模型从原始声音中减去得到的残差。这种残余信号通常被进一步建模为过滤后的白噪声。在这项工作中，我们评估了过滤后的白噪声如何很好地模拟了几种正弦算法中乐器声音正弦建模的残差。我们通过观察残差的“噪声”程度来比较每个正弦模型如何很好地捕捉偏导数的振荡行为。我们进行了一个听力测试，以评估原始残差和模型对应物之间的感知相似性。然后我们进一步研究了残差幅度谱的精细结构是否可以解释听力测试的结果。这里提出的结果有可能资助残差建模的改进。
Nowadays, sinusoidal modeling commonly includes a residual obtained by the subtraction of the sinusoidal model from the original sound. This residual signal is often further modeled as filtered white noise. In this work, we evaluate how well filtered white noise models the residual from sinusoidal modeling of musical instrument sounds for several sinusoidal algorithms. We compare how well each sinusoidal model captures the oscillatory behavior of the partials by looking into how “noisy” their residuals are. We performed a listening test to evaluate the perceptual similarity between the original residual and the modeled counterpart. Then we further investigate whether the result of the listening test can be explained by the fine structure of the residual magnitude spectrum. The results presented here have the potential to subsidize improvements on residual modeling.
