This document proposes a project to gather large amounts of semantic data from music producers during the music creation process. It involves developing plugins that extract low-level audio features and allow producers to annotate them with semantic descriptors. The goals are to (1) collect semantic data, (2) identify correlations in the data, and (3) use these correlations to aid music production tasks. As a proof of concept, the document outlines a mini-project to collect semantic data from musicians and evaluate suitable systems for future research.
