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 …

You need to filter the data at some point. The filter function is a good one to use if you've already created a transfer function\filter, the filter TF is being applied to the data going into the filter in. dataout = filter(TF,datain);
