[Ticket in] B361 - Arc volume levelling issue

Early Access
1

@ivan
With volume levelling enabled I should have -5dB when the loudness is unknown. It remains at 0dB as seen in the below screenshots. The same behaviour is with CarPlay, Bluetooth headphones and the phones speaker. The same for Android. This behaviour occurs with streaming content locally as well as downloaded for offline use.

When the loudness is known it works ok.

Hi, @Mr.Flibble, thank you for the report. I am sorry, from you screenshots, I cannot tell consistenlty if the loudness for this track is unknown. However, I will take a look at the files I have and will compare the results I get in Roon vs. Roon ARC

In the meantime, could you please clarify the following:

  1. How did you figure out that these tracks don’t have the Volume Levelling data? Did you do this via Roon → Show file info? (see screenshot)
  2. If you play the same track in Roon with the same volume levelling setting, which result do you get in the signal path?

Thanks!

Let’s take the album ‘PAINLESS’ by Nilüfer Yanya.

In Roon the album has been analysed and Roon shows a DR of 5 for the album (each track have their own DR).

When volume levelling is enabled to a target of -18 LUFS and if unknown -5dB. Volume levelling is set to albums. The same settings for Arc also.

This isn’t consistent though. I first started giving an example of another album and both Roon and Arc showed the correct volume levelling adjustment.

I have tried several other albums and I was able to reproduce as per my above post.

I have done a pull-to-refresh on the albums page within Arc without success.

I have force closed the Arc app without success.

If I play an album with no known DR analysis in Arc it shows as 0dB instead of -5dB. In Roon the -5dB is applied. I can reproduce this multiple times.

Got it, thank you for the response, @Mr.Flibble. I investigated this one It appears that it’s not a recent problem, moreover, it seems to be a UI issue, the volume levelling is applied when the loudness is unknown, but it’s not reflected properly in the UI. Or do you observe inconsistencies in how the setting is applied as well?

I also created a ticket for our dev team to investigate the nature of this issue as well.

Thanks!

I mainly use Roon/Arc without VL, but as I’m on EA I thought I’d test things from a user perspective to see if there are any errors. I’d need to listen again with and without to determine if it is functioning correctly.

I’m impressed with progress, just a few UI niggles for me.

Update: when it reads 0dB with VL enabled I do not hear a reduction when it is known in Roon to be reduced.

Thanks, @Mr.Flibble, let’s see what our devs will find out in this case.
