My experience: Upsampling kills the music

Mike,

Take it from me... I use to make upsampling dacs. I have tried this in Foobar and other hardware products. I have listened to the settings on the DCS stuff.

Upsampling kills the music. It changes the music that for some seems too make it sound better in the extremes of the Frequecy range (bass & treble). But let's remember that Fourier and LaPlace when they dreamed up the math used for this stuff in the 1800's they where not expecting people to be using it on digital audio. Even though it is written that information can be recoved using this math, the preface was that the math model was infinite in it's capabilities.

In real life most of this is based on 32Bit math and a limited table entry system.

So what happens... well for me it is the loss of the low level detail. The things that make music what it is.

My total preface at this time in my mind is this. Keep the math out of music. Don't add digital filtering (oversampling) math, don't add digital upsampling. Let the music be bit perfect from input too output and the best results will happen.

Thanks
Gordon
