Will upsampling of new DAC make lossy sound as good as Lossless


A question :

 

With most of new DAC’s using their upsampling make a lossy Spotify like file as good as a cd quality .

Most of the DAC’s I see move every file to a very high sampling rate and do a lot of  behind the scene adjustments.

will this “ fill in the blanks “ for lost data and make it good as the original?

It’s my understanding that the purpose of upsampling is not to create new and/or better data, but to move the digital filtering to a much higher frequency so that the steep slope of the filter does not affect the audio band upon conversion to analog.

Upsampling is normally combined with digital filtering to make the analog reconstruction filter easier to build consistently by reducing its order (complexity). Often the digital filtering is linear phase and can correct for the phase response of the reconstruction filter giving essentially perfect phase response overall.

I would agree with your logic 

With all the digital…..Does a recording actually resemble the original ?

The only way this could possibly work is if you used DB poweramp and upsampled MP3 to CD quality 44.1 16bit and then Accurip verified it and filled in what was missing from it's database.

Who knows?
