DSP Issue Over 8 Channels

(1/3) > >>

The Computer Audiophile:
Hi Guys, I think there's a DSP issue when playing music that's over 8 channels. I can reproduce this every time.

Steps to reproduce:

1. Set Output Format to anything over 8 channels (can be 7.1 plus 4 extras or just 12 channels etc....)
2. Play a four channel quad album.

Results - Only three channels will be output.

If I set Output Format to 7.1, all four channels are output.

My system has 12 channels. I'm testing routing audio to the correct channels using the MC Parametric EQ 2 "move" feature. Ideally I can create presets for 4.0, 5.1, 7.1, etc... music so it's routed correctly before entering the convolution filter that's configured for 12 channels.

The Computer Audiophile:
I see that selecting 7.1 output format automatically routes the audio from quad to the right channels.

Why not add a 7.1.4 output format and route the audio correctly for that?

Matt:
I need some help reproducing this.  I have a four channel file.

I play it back at 7.1 or 7.1 with four extra channels.

When I watch Analyzer, I can't see a difference.  Your report is that some of the channels should be fumbled when I add the extra channels.

Can you help me reproduce?  Thanks.

Hi Matt!

Sure thing.

If you look at Analyzer you can see four channels appear in the large window, but look at the volume levels. They are zero for some channels.

Here are two images. One is set to 12 channels and the other to 7.1. Look at the volume RMS at the top.

Matt:
I get SR and SL when I play as 12 channel with JRSS mixing enabled.  Have you picked no mixing instead?
