Convolver for 64 bit v2.1.2

2024-02-11 16:18:02

I was able to find all the components I need to run 64 bit v2.1.2 other than convolver (Convolver-fb2k.component), which I require for both room correction and EQing a variety of headphones.

Is there a different component available at this time that works, or is there any reason a 64 bit version of convolver is not, or will not be, available?

Thanks!

You would need to downmix to stereo multi-channel sources first.

I'll be honest - I have no idea how to convert a mono impulse for EQ for use with the stereo convolver. When I tried using it as-is it just turned all my stereo music into mono. I'm also already using the stereo convolver for something else and I don't think it automatically adjusts gain like the old convolver component did. The page for the old convolver says it was made by Peter, is that a different Peter than the creator of foobar2000 itself? I think that having a convolver that readily accepts EQ impulses you can find online (for headphones) without conversion is a very important feature. The stereo convolver is more useful for something like crossfeed.

The original convolver was made by Garf, but he donated the sources to Peter. As far as I know the core part of the component uses some ancient Intel library that is only available in 32-bits. The component can't be just recompiled to get 64-bit support.

Oh wow, I had no idea. That kinda sucks. Now I need to figure out how to convert mono EQ impulses for use in the stereo convolver...
Thank you for the info!

But what about someone to recompile opensource foo_dsp_convolver for 64 bit?

Whoa, I had no idea that one existed. I'll have to try it out! Thank you again, Case.
