New unsupervised method evaluates deep audio embeddings for music structure analysis

Researchers have developed an unsupervised method to evaluate deep audio embeddings for music structure analysis, aiming to overcome the limitations of supervised learning methods that require extensive annotated data. The study assessed nine open-source deep audio models, extracting barwise embeddings and segmenting them using three unsupervised algorithms: Foote's checkerboard kernels, spectral clustering, and Correlation Block-Matching (CBM). Results indicate that generic deep embeddings generally outperform traditional spectrogram-based baselines, with CBM proving to be the most effective segmentation method. The paper also proposes more rigorous evaluation standards for music structure analysis by advocating for the adoption of "trimming" or "double trimming" annotations. AI
