I'm jumping right in on this thread - I
haven't read what's
gone before in any detail, but here I go...
Have you ever zoomed in on the image of your audio
wave file?
You see a graphical representation of the sound wave.
Zoom right in. You see each point where the wave
crosses over
the zero line in the middle? That's a "zero crossing".
Basically, if you want to cut a piece of audio
(without any
sort of click where it has been cut), it helps to cut the
wave file exactly where the audio line crosses the horizontal
zero line.
This is because the wave will usually have a nice
smooth
transition to the silence following it.
The alternative is to apply a fast fade-out to the
audio,
instead of just cutting it.
If this wasn't clear enough, then I apologise.
I'm rushing,
because I have a very busy few days ahead... Please ask.
Regards
Michael
Thanks Michael. It makes sense. I've used graphical wav editors but I
wasn't aware of this until you explained it.
