In a complex sound editing project, automatic exploration and labelling of the semantic music structure can be highly beneficial as a creative assistance. This paper describes the development of new tools that allow the engineer to navigate around the recorded project using a hierarchical music segmentation algorithm. Segmentation of musical audio into intelligible sections like: chorus and verses will be discussed followed by a short overview of the novel segmentation approach by timbre-based music representation. Popular sound-editing platforms were investigated to find an optimal way of implementing the necessary features. The integration of music segmentation and the development of a new navigation toolbar in Audacity, an open-source multi-track editor will be described in more detail.
