Can't hear anything suspect... Also looking at the waveform and spectrum doesn't show any problem. The problem could be in the playback chain. Do you hear the distortion when playing back the file ?

The 'specs' of the device don't seem to have any meaningful technical content, just marketing blabla. And when I see '32 bit AD/DA', all alarms go off. [1] [1] For an analog signal to have the S/N ratio that 32 bit (in theory) provides, it would need to have a power of more than one kilowatt. Ciao, -- FA
