Out of interest, when using the DSP 'voice levelling', what influences the result?

The reason for my question is I have 2 PC's. Both running JR24. They both share the same music/movie files. One of my PC's uses a Radeon HD 6970 GPU, the other I use a Lynx AES16e PCIe interface card. After running the 'analyze audio' the volume levelling adjustment is different for both. The GPU lowers it by -1.3dB, and the Lynx by -7.0dB.

Is there any reason for this?

(it's volume levelling not voice levelling btw)

not enough info to comment really other than to say playing library items on different machines should produce the same results given the same DSP configuration

do they share the same files but have separate libraries so the files have been analysed separately or share a library?
do both instances have *exactly* the same DSP studio config?

Whoops. Corrected subject title.

You've basically answered my question Matt. 'It's nonlinear'. My PC's share the same files but are analysed separately. Just ran this again and the analysed results are the same. Altering the DSP is what's influencing level adjustment.

cheers.

you mean the reported volume levelling adjustment differs according to the DSP used or that other DSP settings can also cause volume level adjustments? the latter is expected, the former seems odd.

[Wull]

I meant the latter. I didn't realise DSP settings could cause volume level adjustments.

If there is not enough headroom to level, it'll only do as much as it can. If you for example use internal volume and with that create additional headroom, it might level differently, because it can then use that headroom to apply the full leveling values.

Cheers Hendrik. That’s good to hear. I’ve never really dug this deep into jrivers capablility. (Hence all the questions of late). I’ve only just started using the ‘internal volume’ to give my system more headroom. This works well, and what’s very cool is the added bonus of the ‘loudness’ feature. This works really well too. Happy days!
