There was a  like a hum or some or  when they recorded it ?
No. It 's just , it  it 's  it 's not at all uncommon for  for recorded electronics to have different , um , DC offsets.
Or just  ? Huh.
It 's  it 's , you know , no big deal. It 's  you know , you could have ten , twenty , maybe thirty millivolts , whatever , and it 's consistently in there. The thing is , most people 's front - ends have pre - emphasis with it , with zero at zero frequency , so that it 's irrelevant. Uh , but with P L P , we didn't actually have that. We had  we had the equivalent of pre - emphasis in a  a , uh , Fletcher - Munson style weighting that occurs in the middle of P L but it doesn't actually have a zero at zero frequency ,
