Hi everyone,
My attempts to use AL standalone convolver for playing external spdif source have been futile (see my post baby steps with AL). I was wondering if there is anyone who tried using JRiver convoler with an external source pluged to the soundcard? preferably with an RME card.

I have used the JRiver convolver with external sources, with an Atlas Sound card and with a Scarlett as well. So, yes, that does work.

Thanks, is switching between filters a streamline process? can you assign presets or something like that? or is it basic file menu open file etc.

I’ve been over to listen to the new all Wilson 7.1.4 system that Chris Connaker of audiophilestyle.com has put together. He runs his AL filters created by Mitch through JRiver. I did notice that he manually was changing the filter set when moving from 24/48 Atmos files to 24/96 and 24/192 standard MCH files. This may mean that there is not a preset system in JRiver. @Mitchco can likely confirm. JCR

JRiver can automatically switch filters for sample rates.

Ok, Chris confirms the above and clarified his issue with me:

Sample rate switches are easy, but channel configuration switches are hard.

For example,

A 5.1 album has speakers numbered 1 = Front Left, 2 = Front Right, Center = 3, LFE = 4, Rear Left = 5, Rear Right = 6
A 4.0 album has speakers numbered 1 = Front Left, 2 = Front Right, 3 = Rear Left, 4 = Rear Right

Without any channel mapping that changes based on the number of channels being played, the 4.0 track will play the front right and left just fine, but the rear left will go to the center channel and the rear right will go to the LFE. It’ll just play to the first four channels.

I don’t believe JRiver can auto select both the sample rate and number of channels. I could be wrong though.”

But, back to the original topic. JCR

OK thanks. I have never used JRiver. Can someone explain how to configure it for use of external source through the convolver?

Yes, it does. Just set Output Format -> Channels to the system config (and not Output Formatting). Mine is set right now to 5.1 channels and I am playing a 4.0 channel source via a VST3 5.1 plug-in with all channels mapped properly.

So if I use a 3way active xover with sub. Totaling 7 channels with AL I should opt for 5.2 is JRiver? And downmix to 2.1 or 2 as this is a stereo setup?

Oh. I was not thinking of active multiamping. The answer will depend on where/how in the signal path you are doing the c/o. Frankly, I have very little experience with that.

Can anyone please explain how to configure JRiver to play from spdif source through the convoler? What are the steps one needs to take?
Another thing, when configured to use external sources does JRiver become like a "preamp" i.e. can you choose a source manually or does it changes automatically?
