这篇文章描述了从一个声音到另一个声音自动变形的技术。音频变形是通过在多维空间中表示声音来完成的，该多维空间被扭曲或修改以产生所需的结果。多维空间在正交轴上对频谱形状和间距进行编码。在匹配声音的分量后，变形器平滑地内插幅度以在相同的感知空间中描述新的声音。最后，该表示被反转以产生声音。本文描述了变形的表示、匹配技术以及对每个声音分量进行内插和变形的算法。最后显示了一个完整变形的光谱图像。
This paper describes techniques to automatically morph from one sound to another. Audio morphing is accomplished by representing the sound in a multi-dimensional space that is warped or modified to produce a desired result. The multi-dimensional space encodes the spectral shape and pitch on orthogonal axes. After matching components of the sound, a morph smoothly interpolates the amplitudes to describe a new sound in the same perceptual space. Finally, the representation is inverted to produce a sound. This paper describes representations for morphing, techniques for matching, and algorithms for interpolating and morphing each sound component. Spectrographic images of a complete morph are shown at the end.
