Best practice settings for Dithering

Question

Hi,we are transferring shellacs from the 1930/1950.The output is a 32/96 mono WAV file.After declicking, EQing and mastering we offer two formats.A 24/96 flac and a 16/44.1 AIF (Red Book CD Standard).Until now we used a standard setting for dithering in Audition for sampling down. The adaptive noise shaping one.But I wonder if there are some subtleties I may take into consideration, or am I fine? The output itself sounds fine.BestTristan

It will make no difference at all with that sort of material. Even with modern stuff, the dither setting only really makes any difference at the noise threshold. All it does there is stop the output falling off a cliff at -96dB. If you don't use it, and you fade your sound to zero, it will make a jump at -96dB to -infinity dB, and if you had the playback level set high enough, you'd hear that. With dither, applied after any fades, you won't.
