Video 3: Audio Signal Processing using MATLAB

Hello viewers. In this video, some basic processing of Audio signals is presented. Here, it will be shown that how one can implement an FIR low pass filter to remove white Gaussian noise present in an audio signal. Also to produce various sound effects such as Pop, Rock, Jazz etc., a graphic equalizer is implemented. Few other popular sound effects such as Echo, Flange and Reverb are also realized in MATLAB.

This video has following contents: * Basic Filtering: Low Pass FIR filter to remove white Gaussian noise * Graphic Equalizer (10 Bands) * Echo Effect * Flange Effect * Reverb Effect
