They look like they’ve been chopped off because this CD has been really poorly mastered. Audio engineers have been going nuts for about ten years and they think that if something is louder, it’s automatically better. So they use compressor whenever they can, regardless it’s needed or not, and as a result, 95 % of modern records are too goddamn loud (about 10 dB too loud!), the balance between certain instruments is shattered and so is sometimes the balance between certain tones of the same instrument !
It’s really a circus. If it’s some modern CD you were talking about, Britney Spears of other pop “star” for example, you will have to live with shitty mastering. No way to avoid it. Even Iron Maiden’s remasters have been done this way.
Don’t even try to use normalization with it. The damage has already been done and you can only make it worse. Better use volume knob.
