Proposal of the Aesthetic Experience-Oriented Evaluation Framework for Field-recording Sound Retrieval System: Experiments using Acoustic Feature Signatures Based on Multiscale Fractal Dimension

Sound designers and musicians often need to retrieve sound materials based on their similarity to aesthetic hearing experiences from sound databases such as Freesound. This study proposes an aesthetic experience-oriented evaluation framework for a field-recording sound retrieval system, using the sound clips extracted from Freesound. Furthermore, we discuss the features of the framework by analyzing the performance of the similarity search system for field-recording sound material using acoustic feature signatures that are based on the multiscale fractal dimension.
