Hello,

My sound card Juli@ uses ak4358 DAC which applies digital De-emphasis for 32, 44.1 & 48kHz sampling rates.

Is it a good idea to upsample 44.1khz files in order to avoid this?

I donīt know if reading datasheets is necessary when using an already build design smile.gif
The chip applies de-emphasis when a register is set to do so. If this chip is used in a CD Player and the inserted CD shows a pre-emphasis flag the internal logic of the CD-Player sets the de-emphasis register and the DAC applies it. Otherwise it stays off all the time.
