PROBLEMS OF MORPHOGENESIS IN CILIATES. THE KINETOSOMES IN DEVELOPMENT, REPRODUCTION AND EVOLUTION. By Andre Lwoff. New York, John Wiley & Sons, 1950. 103 pp. $2.50. This book consists of two parts: first, detailed observations on the behavior of the blepharoplasts in ciliates; and, second, an attempt to relate these observations to current speculations on the regulatory mechanisms guiding cell ...

We propose a technique of training models for feature extraction using prior expectation of regions of importance in an instrument’s timbre. Over a dataset of training examples, we extract significant spectral peaks, calculate their ratio to fundamental frequency, and use kmeans clustering to identify a set of windows of spectral prominence for each instrument. These windows are used to extract...

While many new interfaces for musical expression have been presented in the past, methods to evaluate these interfaces are rare. This paper presents a method and a study comparing the potential for musical expression of different string-instrument based musical interfaces. Cues for musical expression are defined based on results of research in musical expression and on methods for musical educa...

The similarities between biological and musical acoustic systems has lead to the idea that bioacoustics, and understanding of animal sound production, could provide models for new musical instruments. Physical modeling synthesis of these systems offers the musician the ability to manipulate natural sound, much in the same way s/he would a traditional musical instrument. In this research, the so...

The automatic segmentation of isolated musical instrument sounds according to the temporal evolution is not a trivial task. It requires a model capable of capturing regions such as the attack, decay, sustain and release accurately for many types of instruments with different modes of excitation. The traditional ADSR amplitude envelope model does not apply universally to acoustic musical instrum...
