Seeing the Inaudible. Descriptors for generating objective and reproducible data in real-time for musical instrument playing standard situations

摘要

This article describes a method to generate objective and reproducible data to assist instrument teaching and practicing. The method is based on using audio descriptors and their efficient visualisation that assist in the perception of musical parameters difficult to hear. To aid comparison, we defined and recorded a comprehensive database of positive and negative sound examples from the violin that encompasses frequent mistakes made by students and a wide variety of playing styles.
