Everyone blast mp3 and how it ruined high fidelity. Yet, everyone think dolby digital(ac3) is hifi and i can't contradict them since most concert dvd sound wayyy better than their cd counterpart. Well in fact, ac3 is a psychoacoustic codec similar to mp3 (and less efficient) so we can clearly see the fault is not the format but the audio engineer. The problem is mostly the loudnessrace started in mid 90.
The article author doesn't know anything about mp3 technology and digital audio in general. To say that mp3 codec remove extreme low frequency is completely stupid. These frequency are the easier one to retains. The author should study the basis of psychoacoustic before writing something like that.
