本研究提出 Csound 的 chord_convolver 方法,通过卷积从任意源声音唤起和弦音级内容,对比线性频梳滤波器等并在野外录音中实现音乐应用,最小化伪影。
AI 中文摘要
我展示了如何通过将任意源声音与脉冲响应进行卷积,从源声音中唤起和弦的音级内容,该脉冲响应在听觉范围的每个八度内,每个音级对应一个加窗正弦波的 grain,同时最小化伪影。Csound 用户自定义操作码 chord_convolver 将干 Dirac 分量混入该响应,并应用一次分区卷积。我将该效果与线性频梳滤波器和通用恒 Q 谐振器组进行对比,并结合 Chateau de Lagarde 遗址旁的黄昏野外录音演示了其音乐应用。
英文摘要
I show how to evoke the pitch-class content of a chord from an arbitrary source sound by convolving the source with an impulse response whose grains are one windowed sinusoid per pitch-class, across each octave of hearing range; while, at the same time, minimizing artifacts. A Csound user-defined opcode, chord_convolver, mixes a dry Dirac component into that response, and applies partitioned convolution once. I contrast the effect with a linear-frequency comb filter and with a generic constant-Q resonator bank, and I demonstrate musical use on a twilight field recording alongside the ruins of Chateau de Lagarde.
