I downloaded a video by YTD, I got a MP4 file, and then I opened it by Audacity. The sound was almost all clipped. Almost all the spectrum was cutted/flattened at its edges.
Then, using YTD again, I converted the file in MP3 lowering the volume. Then I was going to open the MP3 by Audacity again.
It was only an extreme try, a curiosity, no hope to see a different result. In fact it's impossible that a clipped sound can magically turn into a regular sound, right?
Well, when I opened the MP3 by Audacity, I realized that the sound was no longer clipped. It was fine, it was whole.
How may it be explained?
