Hello guys.

Ive did a search for this but I found no answer. Im using WavPack a lot recently on high definition files (24/96) and I have a question. I would like to know why WavPack disables the dynamic noise shaping when used with sampling rates above 64 kHz?

Will I get a benefit when I use the switch --use-dns? When using WaveLabs frequency analysis on files that were processed without any switch Im getting dynamic high frequency content over 20 kHz which I assume is quantization noise. When Im forcing the -dns switch this noise is much lower but I think it is still there. Where is it? Is it masked in the lower frequency regions (20-20.000 Hz)?

Thanks in advance for an answer. BTW, great codec!
