0.002 second

When I was playing around with the sound editing program, I found that the stretch function could be very interesting. The original sound was only about 0.002 second long, but after stretched it about 3600 times, the sound is totally different. I am not sure how does the computer work to stretch the sound, but I think when it was stretched, the hidden part exposed. Assuming there are a lot of hidden parts in the original sound, but as the period of the sound is too short, we could not hear all the details. After expended the time period, we could easily hear all the details. The original sound was recorded from the noisy street with a car horn sound. It was a very normal sound we could here everyday, when we heard that, we will only notice the horn as it's too loud. Now, we can hear more sound other than the horn. Surprisingly, there are heaps of interesting sound underneath the horn sound.  Too many layers of sound have been recorded in this piece, because the horn is too loud, we could not easily recognise the other sound. After editing, it is hard to tell what is the original sound. Audience will only notice what they hear.
