How can I avoid this 'clicking' sound when I stop playing a sound?

Question

I really hope this question stays a programming question and do not end up an Sound Mechanics question... Here goes...

I am doing some experiments in order to figure

Answer 1

This is an audio issue, not a programming problem. The click you hear occurs when a waveform is stopped/cut in the middle of a wave, rather than at a zero-crossing.

The best simple solution from a audio paradigm is to very quickly fade-out, instead of just stopping playback.

A slightly more complex solution is to find the next zero-crossing and stop playback at precisely that point.
