I have been experimenting with routing amazon musichd directly into hqplayer version 4. Upsampling and using ext2 filter sounds surprisingly good. However, my set up is a little off at certain frequencies and I have always used roon's eq to adjust for that. That option is unavailable running through hqplayer directly. I am wondering if there is software that allows one to create a eq curve and save it as an IR file for use in hqplayers convolution engine. I don’t need a full room correction solution here, just a simple eq curve that could be used in hqplayer. Ideas?
