Why in the hell would you even care what the wave form looks like. It has no bearing on this subforum.
It is not a processing question. So it goes in this forum.
The important thing is that
ashcat_lt says that it is not something to worry about; he has seen in on many male vocals. He also explained why it happens. As a result, I have been looking at the effect of mic position.
Waveforms are very handy. For example, you can reduce the amount of compression you need to apply, by practicing producing an even waveform. (An even siren is a very good exercise.) On a normal clip, you can see if intensity drops off on certain vowels, too. Then you can work on those vowels. Other things, like trouble with particular consonants or intervals, can cause notes to waver or chatter.
Waveforms are good for looking at onsets, as well. Bad onsets show up straight away -- they are spiky or misshapen.
When I notice something recurring in a waveform, I question it. For this thread, I did actually look first at example traces in the Audacity help, and they didn't show the asymmetry. So, I thought something may be wrong. Some problems you hear first. Others you can see first, before you know what to listen for. And if you manage to eliminate them (if they are actually a problem) from the waveform, you can be sure you've honed your technique, and not just dampened the effect to below hearing threshold.
So, you see, your beeg crusade complex against people posting clips of vocals is misplaced.
Btw, didn't listen to the soundcloud. I think your post is just to suck people in.
"Oh, don't worry about the wave form, your voice sounds great". That what you're looking for?
Anyway, thanks for listening to the clip.
How do I know?
Well, the first thing somebody like you does is go listen to the clip with the intention of ripping it to shreds.
Just thought I'd mention that.
