Why strange look of .wav waveform!!!

[Rayan]

Hello,
I just did a small recording session. Later on looking back I noticed that the vocal track(female singer) is not balanced in appearance. The waveform looks shorter in length on the positiv side of the axis compared to negetive side! I have confirmed by zooming in on regions. It is the same through out the session. Also other tracks seem normal. I cannot believe singer's position can do this cause it is a fixed pattern through out. Does anyone know what can cause this and what is the effect of it? Playing back I can not tell anything bad with the recording. Should this be a concern and how to correct it?

Thanks a lot!

Correct what? The way it "looks"? If you were tape based you'd be happy as a clam with it.

ROFLMAO -- very true!

I think thats what this prob is.

I guess this might have something to do with the microphone element that is pushed backwards more than that it bounces back due to the pressure on the element by the vocals.

The singer only sings in one direction at the microphone, thus the negative voltage of the element is a bit higher. I guess singing at the backside of the microphone (which will look pretty stoopid on some mics) might result in the exact opposite?

Don't do anything to it! Some peoples voices are just that way (assuming you didn't have a compressor smashing her with a fast attack)
Back in the golden age of radio, the DJs used to have a polarity switch. They would use this to take advantage of this phenomenon. If their voice pushed negative, they would flip the switch to make them seem louder over the air. If you have a problem getting her vocals to stand out in the mix, flip the polarity and the problem will go away.
