Intelligent sample rate change

[andersvinberg]

I need to convert a lot of FLAC files of different rates and bit depths to WMA for a system that supports up to 48k/24 (Mercedes Burmester audio).
I obviously want to leave my CD content as is.
A few 44/24 files I want to leave as is.
Higher resolution content I want to convert to 48/24.

Is there a setting that will do that? Down-convert to 48/24 as required, but never up-convert?

Re: Intelligent sample rate change

It cannot selectively do this, however you would not hear the difference between 44KHz and 48KHz, so you are best doing all to 44KHz.
