Audio Signal Processing Simulation in MATLAB

Audio Signal Processing in MATLAB

MATLABSolutions demonstrate how to use the MATLAB software for simulation of a audio signal processing. This tutorial is focused on audio signal processing and it consists of a collection of signal processing examples, which will introduce the basics of MATLAB programming progressively. These examples comprise several topics about implementation of discrete signal processing systems, i.e., digital filter design. Other topics, like simulation acceleration by using c-code programs or GPUs within MATLAB, will also be introduced at the end of the course.

Real time audio special effect generation is an important and one of challenging tasks. This is aninevitable and integral part of any sound casting industry. The requirement of real time design with feasibility has caused a widespread popularity of different digital audio effect generation algorithms. With earlier techniques it was difficult to implement different audio effects. However,invention and popularization of digital signal processing has made the task of audio effects implementation pretty simple compared to analog design.

Special audio effects are used by avariety of sound casting industries like film industry, television, radio, public address system etc.MATLAB is a popular tool which is highly and universally used in the field of signal processing.Simulink, developed by MatlabSolutions, provides an easier block diagram based graphicalprogramming environment. Simulink can be used for modeling and simulating physical systems.The Simulink model is designed without any prior calculation of model parameters thus the model design is supported by trial and error methodology.
