Not with replay gain, not with anything else.
No you cant unclip anything , but the point is that some digital filters and oversamplers makes things worse if the clipping is representerade as consequtive 0dB samples "intersample overs" they internally try to calculate levers above 0dB and some react badly and produces even more distorsion . This effect is real as these kind of signal is out of spec and many DAC and filter chip designers did not consider them to ever be present on a CD . Of course you can have blocks of clipped signal by good old fashioned distortion in the music , but to some filters this is not the same as also "clip" the digital medium by trying to exceed the 16 or 24 bit you have to represent the signal . But as said just lover the volume -3 to -6 dB. But as Julf said you can get this phenomen by to much level by any signal not just loudness war music . But it is also vey common practice to do that on such music . But I would like to see this measured in present day products , but it is telling that benchmark did not consider this until recently ? And they are considered one of the best DAC designers that just not buy a set chips and slap together a nice looking products like most hig end brands . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
