You should work at the highest quality level you can work at throughout your mastering. In other words use the highest sample rate and bit rate throughout the mastering and only at the END of the processing dumb it down to what ever you need for the final export.

thank you for this quick information.

Do you use Crystal Resampler ? or other SRC

If you're using an analog chain, just don't resample. Catch at 44.1kHz and call it a day.

i`ve got the files in 88,2 kHz, that`s the the reason of my question

Right - So "pitch" at 88.2 and "catch" at 44.1 (you'd need two different interfaces - I use different machines, although my main system allows for running multiple SR's at the same time as long as the interfaces are different).

for my understanding.
you run the mix from one computer, go throw you Chain and record the other side with an other computer .

is this correct

Yep. Often on the same machine. Just not with the same interface... But possibly on the same converter set -- The HEDD192 and the Lavry units will run the DA independently from the AD.

oh nice.

for this project i will do it total in the box.

how would you do it in my case.

Now i have one problem
Master in 88,2 -- render with limit -0,2 -- Crystal Resampler will cause overs but UAD Limiter doesn``t work after the Crystal ?
Whats my problem or do i have a wirrle in my head.

I hate to say that in this case, experimentation might be the key... Try it both ways and see what happens - You might find that SRC'ing the source "does less damage" than SRC'ing the finished files. But keep in mind that several of the UAD plugs will dynamically up/downsample the material on the fly also...

thank you very much for your replays,
i will try and give my best.

best regards

i`ve done some test now with my setup (ITB)

Best solution for me is
Mix 88,2 kHz --SRC to 44,1 kHz -- Mastering -- Dithering

Mastering with 88,2 Khz is very good also but i have the problem with the SRC after.
I will have overs after SRC , and when i insert a Limiter after the Chrystal Resampler, the sound will become more pure.......

Viva SRC

overs after src? lower the gain after src. if your src output is
floating point, and your gain algorithm is proper: then any
other change to the sound will occur waaaay below
the 16 bit or even 24 bit noise floor.
then dither to 16 or 24 bits.

in practise, i tend to do a dry run to measure actual post src levels,
and then i make a revision at the master fader output before src.
