Occasionally, I have downloaded some audio from YouTube.
I grab the MP4 and drag it into Audacity to strip out the audio.
It decodes and I see clipping, and go "Oh well..."
For some reason I decided to apply the Amplify tool this time:
It (by default in this case) picked a small amount of attenuation. Huh? I say to myself.
I zoom way in on some of the clips, and find samples that exceed "full scale", the biggest by about 14% (not shown)
So I apply the suggested attenuation to the whole piece...
And the "clipped" peaks are restored. (Sorry about the scale change, makes it look smushed, but it isn't)
What's going on here?
If I burn a disc (yes, I still do that) without the attenuation, it gets clipped, sounds doubly awful.
With this new insight, I can burn the disc, and it only sounds singly awful.
What's with the over-scale yet restorable sample-hiding here?
