Hi

I took a wav file which is recorded as 44.1 KHz 32 bits float (A) and played it through a DAC (Topping NX4 DSD) which I recorded the output through an iD14 as 96KHz 32 bits float (B).

Then I opened the spectrogram view through Audacity of both to check the difference and B is full of stripes at regular interval. I wonder what could be the explanation.
