a guerra da altura

Não sabia nada desta Loudness War que o Julian Gough refere, mas a verdade é que compreendo perfeitamente aquilo de que ele está a falar.

Record companies want their albums to sound louder than the other guy's album, in shops, on your hi-fi, wherever, because people tend to think that the louder of two songs is the better of two songs. That’s just the way our brains are wired.

So record companies have been boosting the overall loudness of CDs. But there's a maximum loudness limit to the digital signal on a CD. Increasing the overall loudness increases the loudness of the quiet bits: but it doesn't (it can't) increase the loudness of the bits that were already at maximum loudness.
