Digital signal processing is being increasingly used for audio processing applications. Digital audio effects refer to all those algorithms that are used for enhancing sound in any of the steps of a processing chain of music production. Real time audio effects generation is a highly challenging task in the field of signal processing. Now a day, almost every high end multimedia audio device does digital signal processing in one form or another. For years musicians have used different techniques to give their music a unique sound. Earlier, these techniques were implemented after a lot of work and experimentation. However, now with the emergence of digital signal processing this task is simplified to a great extent. In this article, the generations of special effects like echo, flanging, reverberation, stereo, karaoke, noise filtering etc are successfully implemented using MATLAB and an attractive GUI has been designed for the same.
