Weird questions about redithering
« on: August 29, 2008, 03:06:01 pm »

Hi,
a)If you re-import a 44k/16 file you have just mastered (originated from a 44k 24 file) into your typical working session at 44k 24 and just invert PAN (LR to RL), for example. Do you need to redither to go again to 44k 16?

I am aware that every bit truncation needs dithering, but in such funny situation, only zeroes are being applied from bit 17 to 24. Or not?

b)If you Audiosuite a stereo  file, which has Dither as adefault inpreferences, then at latter processing  you need to bounce and dither to go to 44k 16.. Can it be harmful to the file since it is being double.. triple dithered?

c)Between Power Dither (Level 1,2,3) and TC MD3/4. which one suits best a mastering scenario?

I am asking these curious stuff because for the first time in 10 years of mastering, a client complained that he could listen to dither at his Sony Discman headphones. Smile

Obviously I cured it by cleaning the beginning of the song, followed by a quick fade-in. But now, sound starts almost from nowhere/silence.

I think (and someone please correct me if I am wrong) that since there was already dither applied to the lsb once you shouldn't have to do it again.  The 24bit file will have captured the dither that already exists on the 16th bit.
