We propose a microphone array network that realizes ubiquitous sound acquisition. Several nodes with 16 microphones are connected to form a novel huge sound acquisition system, which carries out voice activity detection (VAD), sound source localization, and sound enhancement. The three operations are distributed among nodes. Using the distributed network, we produce a lowtraffic data-intensive ...

Concatenative data-driven synthesis methods are gaining more interest for musical sound synthesis and effects. They are based on a large database of sounds and a unit selection algorithm which finds the units that match best a given sequence of target units. We describe related work and our CATERPILLAR synthesis system, focusing on recent new developments: the advantages of the addition of a re...

The inverse problem for time-harmonic acoustic wave scattering to recover a sound-soft obstacle from a given incident field and the far field pattern of the scattered field is considered. We split this problem into two subproblems; first to reconstruct the shape from the modulus of the data and this is followed by employing the full far field pattern in a few measurement points to find the loca...

In this paper we introduce a prototype that is designed to produce forensic sound network data recordings using inexpensive hardand software, the Linux Forensic Transparent Bridge (LFTB). It supports the investigation of the network communication parameters and the investigation of the payload of network data. The basis for the LFTB is a self-developed model of the forensic process which also a...

Contemporary use of the term ’intension’ derives from the traditional logical doctrine that an idea has both an extension and an intension. In this paper we introduce an intensional FOL (First-order-logic) for P2P systems by fusing the Bealer’s intensional algebraic FOL with the S5 possible-world semantics of the Montague, we define the intensional equivalence relation for this logic and the we...

abstract background: given the fact of irrecoverable consequences of noise in industrial societies and the environment, acoustic filter (silencer) is an instrument which obstacles the transmission of sound waves. a sort of this silencer is helmholtz resonator (branch amplifier) which comes to sound appropriate for low and below 200 hz frequencies in fan and channel noise. the purpose of this ar...

This paper presents a data-driven approach to the construction of mapping models relating sound features and blowing pressure in recorder playing. Blowing pressure and sound feature data are synchronously obtained from real performance: blowing pressure is measured by means of a piezoelectric transducer inserted into the mouth piece of a modified recorder, while produced sound is acquired using...

We present recent works on the representation of spatialization data for the authoring, interchange and rendering of spatial audio in musical contexts. These works are mainly implemented in the OpenMusic computer-aided composition environment. High-level structures created in compositional processes are represented by matrices, stored using a standardized interchange format and finally read and...
