An audio descriptor describes the information of an audio signal in a compact and precise representation. There are various standards available to extract the audio information in various ways to be used for particular applications such as, speaker recognition, musical instrument identification, singer identification, multimedia database indexing, genre detection and so on. There are various au...

In [Wu], the noncommutative Atiyah-Patodi-Singer index theorem was proved. In this paper, we extend this theorem to the equivariant case.

The analytic approach to spectral flow is about ten years old. In that time it has evolved to cover an ever wider range of examples. The most critical extension was to replace Fredholm operators in the classical sense by Breuer-Fredholm operators in a semifinite von Neumann algebra. The latter have continuous spectrum so that the notion of spectral flow turns out to be rather more difficult to ...

The singer’s information is essential in organizing, browsing and retrieving music collections. In this paper, a system for automatic singer identification is developed which recognizes the singer of a song by analyzing the music signal. Meanwhile, songs which are similar in terms of singer’s voice are clustered. The proposed scheme follows the framework of common speaker identification systems...

As one of the techniques enabling individual singers to produce the varieties of voice timbre beyond their own physical constraints, a statistical voice timbre control technique based on the perceived age has been developed. In this technique, the perceived age of a singing voice, which is the age of the singer as perceived by the listener, is used as one of the intuitively understandable measu...

Peter Singer is used to controversy—indeed, he seems to court it—but nothing could have prepared him for the reaction which followed his recent review of Midas Dekker’s Dearest Pet for the on-line version of Nerve magazine. Dekker’s book is a social, historical, and psychological examination of bestiality, and Singer’s review has been widely perceived as condoning the practice. The horrified re...

The Hochschild and cyclic homology groups are computed for the algebra of ‘cusp’ pseudodifferential operators on any compact manifold with boundary. The index functional for this algebra is interpreted as a Hochschild 1-cocycle and evaluated in terms of extensions of the trace functionals on the two natural ideals, corresponding to the two filtrations by interior order and vanishing degree at t...

We establish a splitting formula for the spectral flow of the odd signature operator on a closed 3–manifold M coupled to a path of SU(2) connections, provided M = S ∪X , where S is the solid torus. It describes the spectral flow on M in terms of the spectral flow on S , the spectral flow on X (with certain Atiyah–Patodi–Singer boundary conditions), and two correction terms which depend only on ...
