Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. signal processing on the received acoustic waves include interpolation, decimation, data filtering and reconstruction. Audacity is an easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The short-time phase spectrum is not considered as perceptually signiflcant as the corresponding magnitude or power spectrum and is omit-ted in the signal representation [1]. For audio signal processing, real time is only important when either or both input and output are live audio. A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. Programmable DSPs and SOCs, with architectures designed for implementing complex mathematical algorithms in real-time, can efficiently address all the processing needs of such a system. b.
