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 …

For audio signal processing, real time is only important when either or both input and output are live audio. – Audio input comes from microphone, audio output goes to speakers or headphones. What about latency? – Not important if either input or output are not live. E.g. consider playing recorded music.
