The LEEDH processing theory is really interesting; in that what is the cause of the sound improvement?
To vastly simplify, for each step of the digital volume control LEEDH uses a whole number. i.e instead of 3.14141414141414 into infinity they use 3.141
So does using exact numbers mean greater accuracy and thus better sound? Or is it the whole number has far less math overhead, so the substrate of the chip itself is not working as hard, leading to lower noise and thus better sound?
The math theory is very interesting.
Either way finally we can have digital volume control that sound decent, because it never could compare to an analog volume.
