Hello guys.
I´ve did a search for this but I found no answer. I´m 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 WaveLab´s frequency analysis on files that were processed without any switch I´m getting dynamic high frequency content over 20 kHz which I assume is quantization noise. When I´m 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! -------------------- http://marlene-d.blogspot.com/

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.
