Greetings. Am building a dac with dual 9038pro chips with only usb input. Me and my friend are building it together. The rest of the circuit is pretty much done. We would like to put in an upsampling circuit for the 9038. Does anyone have any ideas on this?
Upsampling circuit is already exists inside the 9038, but if you want to put your own, you can use many Digital Filters os ASRC, for example PDM100, DF1704, AK4137.
