Many years ago, I was learning how to whistle like the other boys of my school, I noticed that I was able to do much more (and this, even if I could not still whistle!). Indeed, I managed to reproduce very strange sounds without really knowing how in fact, which astonished so much people who were looking for my secret :-)
With the years, my voice has changed and some sounds disappeared like birds noises too difficult to make for example. But sometimes I make these noises again to make people laugh.
You will so find here what I called "sounds from elsewhere" … sorry for quality !
