Advancing Audio Phylogeny: A Neural Network Approach for Transformation Detection

In this study we propose a novel approach to audio phylogeny, i.e. the detection of relationships and transformations within a set of near-duplicate audio items, by leveraging a deep neural network for efficiency and extensibility. Unlike existing methods, our approach detects transformations between nodes in one step, and the transformation set can be expanded by retraining the neural network without excessive computational costs. We evaluated our method against the state of the art using a self-created and publicly released dataset, observing a superior performance in reconstructing phylogenetic trees and heightened transformation detection accuracy. Moreover, the ability to detect a wide range of transformations and to extend the transformation set make the approach suitable for various applications.
