A two-port electroacoustic analogous circuit model for finite-length acoustic horns belonging to Salmon’s family of horns is described. The circuit is useful for simulation of horn-loaded electroacoustic systems with electric circuit simulator software such as SPICE ~simulation program with integrated circuit emphasis!. An implementation of the circuit model for use with the PSpice simulator so...

Camouflage voice is the common check material form in judicial voice testing field that brings about many difficulties to speaker identification. Aiming at the electroacoustic disguised voice, we get fundamental frequency variation rule before and after voice change of multiple corpuses by analyzing map and data. The results show that the fundamental frequency before and after voice change exis...

This paper introduces the TaCEM project (Technology and Creativity in Electroacoustic Music), funded for 30 months by the Arts and Humanities Research Council in the UK, investigating the relationship between technological innovation and creative practice in electroacoustic music of the last 40 years (http://www.hud.ac.uk/research/researchcentres/tacem/). It is a collaborative project between t...

The TaCEM project (Technology and Creativity in Electroacoustic Music) has investigated the relationship between technological innovation and compositional processes on the basis of nine case studies, including John Chowning’s Stria (1977). Each case study involved researching the historical and contextual background of the work, emulating the technology used to create it and analyzing its musi...

In multivariate systems, when it comes to identifying actual operating conditions ranges, or optimal settings, the use of constrained optimization is often required. Among the different tools for the engineer to perform such optimization, designed experiments offer accurate performances. In this paper, the optimization process of ‘‘electroacoustic absorbers” is investigated by means of response...

A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...

Presenting musical composition on a multi-channel loudspeaker configuration has now been practiced for over 60 years. Pierre Schaeffer in partnership with Pierre Henry composed a number of works, one of the works was Symphonie pour un Homme Seul (1950). The composition was presented on a tetrahedral configuration, which consisted of a frontal pair, a single rear and one elevated loudspeaker (Zv...

This article discusses in detail the use of spatial references in electroacoustic music, which is the fourth of the five senses of space I identified in a broader investigation on the meaning of space in music, electroacoustic music and sound art. The expression space as reference refers to the use of the referential properties of sound to suggest or produce spatial impressions and associations...

The "Jesús Guridi" Conservatoire of Music, Vitoria (Spain) is a centre committed to creating and spreading contemporary music via its educational activities and an ongoing offering of concerts, festivals, meetings, conferences, seminars and master classes. Since its beginnings it has organised numerous activities dedicated to the creation of contemporary music, enjoying the participation of com...
