Just received the Crane Song analog dither CD. Per their instructions, I mixed it into a tune I'm mastering (recorded/mixed on ProTools LE at 16/44.1 I think - took the CD-R & D/A'd it out of my TASCAM CD-RW2000 (24 bit), ran it across my tube A/D at 24/88.2 & into the DAW - which was a huge improvement in itself). I could not believe what I was hearing! All of a sudden my sound had depth and (just like they said) life & warmth! When I muted the dither track, my "so much better" hi-res track now sounded thin & flat. Unbelieveable. How do they do that?!? I have found a secret weapon (Ha, Ha, Ha. I am ZATAR!!!). One thing I'm not sure of is if I'm supposed to run the dither track through any processing that I'm doing to the audio track or if I'm supposed to just leave it alone & route it to the main bus untouched? Input??? I suppose now somebody is going to tell me that there is even better dithering out there somewhere.
