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/

Ah, now I understand.
If you are using it lossy then is there any advantage to leaving it as 24/96? |

I don´t like to resample and other codecs like AAC or WMA-Professional simply discard everything above 20 kHz. I would like to keep them & save space at the same time. The lossless compression eats away too much of my limited space. -------------------- http://marlene-d.blogspot.com/
