The sound of violins have always intrigued musicians, composers and…scientists.From the beginnings measurement methodologies of the phenomena that concur to the production o sound have been refined, e.g. modern scanning vibrometers allow us to accurately reconstruct in a few minutes the modal shapes on the whole instrument, while just a few years ago this operation could last several days. Generally speaking, the breakthrough of digital computing represented a tremendous boost for several directions of research of violins sound.  In this contribution we investigate on the use of machine learning for analyzing the timbre of violin sounds.

Melody extraction algorithms are designed to automatically obtain a sequence of frequency values corresponding to the pitch of the dominant melody from a musical recording. Over the past decade melody extraction has evolved into an active research topic, comprising a large variety of proposed algorithms spanning a wide range of signal processing techniques.
This article, which is a summary of a recently published paper [1], illustrates the challenges inherent to the task and provides a brief overview of some of the most relevant strategies to melody extraction, the applications for which melody  extraction is useful, and the challenges that remain.

‘Virtual analog’, which refers to the modeling of analog musical equipment, has been a lively topic in research and consumer electronics for two decades. It is an exciting branch of audio signal processing, as there are still major unsolved signal processing problems to be tackled and the results lead to great sounds.

I am delighted to be stepping into the role of TC chair this year, and slightly nervous whether I will be able to do as good a job as my highly successful predecessor Shoji Makino. Thanks for handing things over to me in such good shape Shoji. I will do my best to maintain the standard.
