The voice

-January 24, 2013

Do you remember Ernie Kovacs? Ernie Kovacs was a television comedian in the 1950s. Please see this link for a little biographical info.

In one of his sketches, he sang a dreadful rendition of "Mack The Knife" from which I took a screen shot of his voice waveform  

Next, I graphically extracted data from the screen shot for what came to be a total of 947 data points. From a casual inspection in Excel, reproduction of the original waveshape turned out reasonably well.

 

 

Next, I normalized the voice data to a root-mean-square (RMS) value of one-hundred and calculated two key ratios, the peak to RMS ratio and the peak to average ratio of the absolute values. Respectively, they are very nearly three to one and four to one.

This is by no means definitive of these two ratios for the human voice, but these particular examples seem to  give some reasonably good insight about what to expect them to be when doing audio work.

I just have to add just a little bit more about Ernie Kovacs. 

Please learn a little about the word "solfeggio" by taking a look at this link.

 .... and then go look at this You Tube video

Note the baton get turned into a banana. You're in for a real treat.
