Hi I need some help here... I have the same track from two different sources. Both are in uncompressed WAV but one has used some processing that does not let it go past the horizontal white lines in Edit View... Here is what I mean:
It looks like the second wave is using the Hard Limiting effect, with the max amplitude set to -1 dB. Personally, I would use Normalize instead (it doesn't distort the wave at all, it merely decreases the overall amplitude) but that's not what your second image is showing.
