If I upsample digital flac 16/44 to hires 24/192 is the sound equal to native 24/192


sam here again. Using jriver media when i upsample from commercial digital download flac 16/44 to flac 24/192 and then check the spectrogram of the upsampled file i get this. https://i.postimg.cc/3JbvJ7pg/07-Ebony-Eyes-Bob-Welchflac.png

When i upsample the same commercial digital download flac 16/44 to flac 24/192 using foobar2000 and the multimedia dsp filter using the preset zero order hold https://i.postimg.cc/pTt0GKLX/zero-order-hold.png the spectrogram looks like this. https://i.postimg.cc/K82DymyJ/07-Ebony-Eyes-Bob-Welch-French-Kiss-1978-digital-vinyl-wav.png

When i play the upsampled 24/192 zero order hold file in voxengos span filter to check the wave form i get this. https://i.postimg.cc/MTSS7Mk1/span.png

Bonus: sample 1 copy at 16/44 with old piece of wood placed on the p.c power chord at the wall socket to encode the natural wood frequencies and tone onto the digital audio.http://u.pc.cd/BpbotalK

It all depends on what device or process you are using to upsample your music.

No, not really.  No upsampling algorithm can reproduce harmonics as in the original session. 

They can however improve the frequency response and jitter performance of the DAC.

I've tried both ways and I'm not a fan of upsampling/DSPing at all. A little upsampling (to DSD perhaps) can sometimes make a poor DAC sound more euphonic...sometimes.

HuH? 
When it comes to upsampling/downsampling/filtering/DSPing...  One mans sugar may be another mans sand...
