There are many reasons for that... it is impossible to give a diagnosis based on so scarce information. For example, if you did code a filtering program using an FFT, did you remember that FFT is analogous to a circular (and not to a linear) convolution ? For this reason you must implement either the overlap-and-save or the overlap-and-add technique. Failing to do so is one of the possible reasons for clicking and popping audio. Internet is full of references to those two techniques. Google is your friend here. 73 Alberto I2PHD
