Distortion is a desirable effect for sound coloration in electric guitar amplifiers and effect processors. At high sound levels, particularly at low frequencies, the loudspeakers used in classic style cabinets are also a source of distortion. This paper presents a case study of measurements and digital modeling of a typical guitar loudspeaker as a real-time audio effect. It demonstrates the com...

Introduction There are several possible mechanisms that might underlie perceptual excellence, which we can describe by reference to a metaphor regarding audio amplifiers. There are several factors that limit a physical device such as a radio receiver. First, the internal amplifier has some intrinsic noise, which gets amplified along with the radio signal. Second, the radio tuner may be unaccept...

A control-theoretic approach in designing Digital to Analogue Converters and Digital Amplifiers which leads to improved performance in Audio and Multimedia applications is presented in this paper. The design involves an over-sampling and a pulse modulation component which is driven by a pulse generation algorithm based on the characteristics of the output filter. The theoretical model results i...

Now-a-days the new family of dc-dc converters based on three state switching cell and voltage multiplier cells. It present a demonstrate of some advantages and limitations of a several topologies were typically use in voltage step-up applications. The operating principle of this family has chosen the boost converter and discussed in detail. The analysis of converter can applicable in uninterrup...

This papers presents the simulation work on Gigabit Passive Optical Network over Free Space Optical Communication channel for triple Play services proving access of Audio Data and Video to 128 Users. The System is simulated and results are taken in terms of QFactor and BER. Various investigations for system evaluation are also performed such as integration of amplifier into system. System is al...

Orthogonal Frequency Division Multiplexing (OFDM) has become increasingly popular due to its potential applications in digital audio broadcasting, digital terrestrial TV broadcasting, and satellite communication. A notable drawback of OFDM systems is their sensitivity to nonlinear distortion. For maximum power efficiency, amplifiers and transmitters of modern communication systems often operate...

The Immersive Computer-controlled Audio Sound Theater (ICAST, pronounced “eye-cast”) is an on-going research project that addresses performance issues in electroacoustic music. By exploring a variety of differing performance modes through a computer-controlled loudspeaker environment that is malleable, adaptable and intuitive, we are able to explore new and novel metaphors for sound control usi...

Changes and developments in the times of society are required to be able keep abreast technological advances. The development field electronics technology certainly requires human resources who have competence accordance with needs industry., results observations carried out on Serdang Kulon village, there still many community members do not understand so it is very necessary carry service acti...

Multi-channel sound diffusion has been an essential part of the electroacoustic music process from the very beginning of the genre. We see early experimentation in sound spatialization in Varèse’s use of loudspeaker “paths” in Poéme Èlectronique, Stockhausen’s experiments in quad and cubebased speaker arrangements (Chadabe 1997), and Chowning’s computational approach to sound diffusion in works...
