Automatic Audio Morphing on Detached Sound Waveforms

Abstract

Abstract-This paper describes the techniques to morph between the two portions of sound originated from a common source, broken because of by some reason. We make use of morphing technique to join the sound where the pitch of the sound slowly changes from one broken part to another broken part by slowly changing the pitch information also covering the unvoiced region of the music. Spectral shapes are encoded on the multidimensional space while pitch on orthogonal axes of it. After matching components of the sound, a morph smoothly interpolates the amplitudes to describe a new sound in the same perceptual space. Finally, by inverting the representation, sound is produced. According to the literature survey, this is the first paper which explains the step by step evolution of one sound resulting into other sound across all states of intermediate steps along with the step by step runtime analysis. This will help researchers in future to improve the morphing methodology by looking carefully into the intermediate steps which decides the overall results. Here, we key out representations for morphing, techniques for matching, and interpolation algorithms and morphing each sound component. Spectral images of complete morph spectrogram are shown in the end.
