Upsampling - but seriously folks


Any fans of upsampling out there? Anyone have experience with upsampling in which it actually makes your source sound better?

Personally I don't see how it can possible make any difference, but I'd like to hear from those of you who have had a positive experience.

Jim,

Well, it won't give you more data, but it may push any noise up a few octaves, whether you like that or notice it or not may have a lot to do with your DAC.  There's no 1 way to do upsampling though. Of course, you can draw a line between samples and extrapolate but companies like Wadia spent a lot of time making fancy, Bezier curve fitting algorithms as well. 

I've always meant to try up and downsampling using a free tool like ffmpeg to try files at different resolutions.  Why don't you give it a shot and see if you can tell any difference?

Best,

Erik
DSD is another thing.  The noise performance of normal DSD is normally pretty poor compared to 44/16 PCM, so it may in fact be a very good thing to do. In this case the argument is entirely about noise performance.

Who can hear it and when can they hear it, that's another thing.

Best,


Erik
