Situation: I have a Platin Stereo Hub HT.
I’m using 2 streamers for Roon: the built-in one and the second is Ropieee running a Raspberry Pi 4 connected to the USB port of the hub.
Although using the same muse presets and settings, I do get different signal paths. In one case it is High quality (green dot); in the other case it is enhanced (blue star).
Any one can enlighten me where the diff comes from?
[Moderator edit: order of photos corrected:]
Because you have all sorts of DSP actions going on hence the blue enhanced. Headroom, convolution, parametric equalizer etc.
Vs the first example is unmodified hence the green regular high quality.
Sorry, the pictures are not in the correct order. The first picture follows the second picture (green). And I’m doing the same dsp in both cases, at least that’s what I think I’m doing.
Ah yes, I see now, sorry my bad.
I wonder if this is because the Platin Stereo Hub on its own is not reporting all of its actions to Roon correctly hence the high-quality green dot only?
Both are probably doing the same DSP work as shown by the processing speed being similar.
A good question though.
The green dot is present because the Platin Stereo Hub is performing a sample rate conversion from 44.1 to 96 KHz, whereas the RPi4 running Ropieee isn’t preforming such a function. I think I’m correcting in saying that when such a conversion takes place outside of Muse (as is the case with the Platin Stereo Hub) it shows as a “high quality” rather than “enhanced”.
Yes, makes sense. No green light if the source file is already 96kHz and no conversion needs to be done by the hub.
I’ve adjusted them, so they should look ok now.
I think you are basically correct, but it it seems that it’s not the upsampling that causes the green “High Quality” nomination, Roon seems to think that the final transmission from the Platinum Hub upsample and WiSA wireless link is lossy.
Whatever the reason, there are two differences in the signal paths:
Basically, the Ropieee transfer should likely have a gren dot as well, as i suppose the speakers are getting the audio signal in a similar way in the end.(But Ropiee is not aware)
