This video feels like the culmination of why certain Audiophiles distrust various, unique approaches to making music sound better.
Maybe it works but the presentation and the content are very difficult to take seriously. I was born in the late 70’s and love and to listen to music. I would guess a high percentage of all the music I have listened to in my lifetime has been digital, hasn’t been a barrier to me connecting emotionally to music. Very strange presentation and study.
The elephant in the room for me would be a DAC converts a digital signal to analogue, at that point, wouldn’t the conversion correct the perfect waive issue? Algorithms are already used in certain types of DAC’s, FPAG’s and I think they are also used in DSP software. Would wonder what makes this particular algorithm unique in solving an issue that would be hard to even proof exists.
This post got me thinking deeper than I anticipated I would, kudos to the OP for that.
