Freischütz Digital: A Case Study for Reference-Based Audio Segmentation for Operas

چکیده
Music information retrieval has started to become more and more important in the humanities by providing tools for computer-assisted processing and analysis of music data. However, when applied to real-world scenarios, even established techniques, which are often developed and tested under lab conditions, reach their limits. In this paper, we illustrate some of these challenges by presenting a study on automated audio segmentation in the context of the interdisciplinary project “Freischütz Digital”. One basic task arising in this project is to automatically segment different recordings of the opera “Der Freischütz” according to a reference segmentation specified by a domain expert (musicologist). As it turns out, the task is more complex as one may think at first glance due to significant acoustic and structural variations across the various recordings. As our main contribution, we reveal and discuss these variations by systematically adapting segmentation procedures based on synchronization and matching techniques.

Frame-Level Audio Segmentation for Abridged Musical Works
Large-scale musical works such as operas may last several hours and typically involve a huge number of musicians. For such compositions, one often finds different arrangements and abridged versions (often lasting less than an hour), which can also be performed by smaller ensembles. Abridged versions still convey the flavor of the musical work containing the most important excerpts and melodies....
