Hello,

If I zoom in on any wave file I see small jagged distortions in the wave. Is there some way to 'smooth' these out ('Smooth' itself seems to change the wave and sound too much). This is voice data that must be encoded with video for web delivery -- we're looking for ways to pack more quality in the data stream by reducing noise.

Thanks,
Rusty

Why do you want to do that? does it sound bad?

I don't think that these jagged lines are necessarily a bad thing. Some waveforms have this appearance. If everything sounds okay, I wouldn't worry about having to smooth out your waveforms.

Its only a concern to me because each of those little zigzags (and I'm talking about the ones you only see at full magnification that ride on the main wave), I would think, must be encoded. You do not need all those little zigzags. Its random noise at that level. And its not the way it sounds that I'm considering at all -- its how well it compresses for web delivery. Maybe the newer codec (or even older -- this is a new area for me) know to remove these little guys. It would seem a simple matter to remove them but from the sound of the replies so far, maybe not, or maybe its not that important.

Thanks!

Those little zigzags are probably high-frequency. Try using eq to eliminate then. Most low bitrate encodes won't reproduce the high frequencies anyway.

This whole thread is ridiculous!

Man, quit worrying about this unimportant thing!

People worry too much about what they see on a monitor instead of what they hear!
