Convolution Filters

(1/2) > >>

YankeeInLondon:
When I stream music I use Ameba Audio's SoundSource which has the full catalog of AutoEq parametric filters. I'm no expert on this so maybe I'm making a dumb mistake but when I use these same filters -- which are JSON files in structure -- with JRiver Media Center 29 -- I get the message the file is "not valid" while at the same time it says "Enabled and Processing" at the top:



When I click on the DONE button, It moves me from A to B:



Can anyone help me get this figured out?

mattkhan:
convolution is described in https://wiki.jriver.com/index.php/Convolution

it's a bit hard to comment as it's hard to know what you're trying to achieve and/or why you think MC convolution would be compatible with such a file (i.e. it's not)

perhaps if you explain what you're trying to do then someone can point you in the right direction

YankeeInLondon:
I am interested in listening to convolution files with JRiver Media Center. I don't suppose that the convolution/EQ files I have are the same but I had hoped they were. I have a suspicion that these files will need to be sampled to a particular sample rate and converted to that sampled format but I'm really just guessing. My question is ... how do you use this feature? I didn't see any documentation on this and so I'm looking for help and the UI is not helping me get a grip on where I'm failing.

I don't know what the 1st bit means, the convolver is used to apply a filter to whatever you want to listen to.

The link in my previous post explains how to use the MC convolver.

YankeeInLondon:
I thought the most common usage was for headphones and there are databases of these filters available (e.g., Crinical, Innerfidelity, Headphone.com, etc.) which makes the getting started cost far lower than bespoke measurements. This is indeed what I am using for streaming music via the SoundSource app from Amoeba Audio. A popular repo for producing these filters is [AutoEQ](https://github.com/jaakkopasanen/AutoEq) and in reading the author's [notes about MacOS](https://github.com/jaakkopasanen/AutoEq#osx--macos) he refers to the catalog of parametric filters in SourceStream as being the best place to start. I already was using SourceStream but hadn't realized this feature was added until recently. I have carefully extracted all the configuration for my headphones and was hoping I could use them in JRiver (not just streaming).
