To meet the challenge of analyzing and visualizing large music corpora, we have developed a web platform that simplifies the path from raw data processing to data visualization, search and comparison. Our platform can process both symbolic (MusicXML) and audio data, allowing users to easily access and compare different corpora. It provides a web-based interface for intuitive browsing and filtering as well as comparison of selected features of music pieces. It simplifies the exploration and comparison of growing digital music collections and speeds up the analysis process for users with different levels of knowledge.
