Now, if you have any use of Roon’s DSP engine, that data is changed. There again, it’s maths on data, not on music. There aren’t multiple ways of using maths to do EQ or whatever the engine allows, there is only one.
That makes it quite impossible for Roon to have variance in sound quality between versions.
It seems that there are at least two calculation ways for DSP: the correct one and the Roon one.
There currently seems to be an issue with Roon’s phase inversion feature, whereby any clipped samples are ‘wrapped around’ and instead of just clipping at positive 0dBfs, will go to negative 0dBfs, creating significant distortion.
This can be audibly demonstrated very easily by playing a track with samples at 0dBfs, or that contains intersample overs.
If you listen to ‘Bon Voyage’ by Droeloe ( https://song.link/gb/i/1170076107 ) and then enable phase inversion as shown:
