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!

Does this even make sense? WavPack is lossless, so the only effect of different switches would to be to change the packing efficiency, not to change the audio content.
