That should be easy. Make a new mono wave file and add for example 8192 samples silence. Put one sample as high as possible somwhere in middle. I suggest you to edit mono file at this stage, because if the impulse differs between channels, I think it can result small delay and/or gain difference between channels. Now you should have impulse responce which doesn't do any "efects". Now you can apply some efects with Adobe Audition to it. Just duplicate the mono file to stereo afterwards. Impulse responce should be at same sampling rate as the audio where it is applied.

Old stuff is still very useful, old threads move to the bottom of forums so the ones noone is ever going to reply to annoy noone, and if someone wants to resume discussion of an old topic, perhaps something to do with recent developments, they can do so without having to repeat everything that has already been said.

I'm not quite sure how to correctly use the convolver plugin. In my case I would like to use it as an alternative to Dolby Headphone. I have an impulse file from a rehearsal room, but I assume that it isn't enough to only use the convolver plugin, because the stereo field still seems to be unnaturally wide. Would a simple crossfeed plugin, that's put before the convolver plugin, be the best solution here?

I suppose so. I don't think that it matters much if the crossfeed DSP is before or after the convolver, the results should be almost equal.

Is there a way to get the convolver to work with 6-channel audio? I don't even need seperate impulses for each channel, just one to apply to all.

I think I've fallen love in... Many thanks!

I'm running foobar2k v0.9.4.4 and I get en error stating that foobar "Failed to load DLL: foo_convolve.dll
Reason: This component is missing a required dependency, or was made for different version of foobar2000."

So, how do I fix that?

same here. Dependency Walker highlights files mpr.dll & wzcdlg.dll.
even after downloading and placing those files in foobar & system32 directory, same problem occurs on launch.

I have no problem. it's work fine.

It is not recommended to attempt to fix component loading problems by downloading random DLL files and placing them all over your hard drive. Unless you know exactly what you are doing, you will likely do more harm than good, if you achieve anything at all. Also note that the Dependency Walker FAQ has an entry dealing with MPR.DLL.

Which version of foobar2000 do you use? The convolver DLL that is linked to in the first post is made for foobar2000 0.8.x. If you use 0.9.x, you will have to get the convolver version from the official additional components page.

Ah, downloading from the components page instead of from the link at the beginning of the thread fixed it (of course, since I'm running an 0.9 version...). I'm pretty sure that it wasn't obvious that the link in the thread was for v0.8 when I downloaded though. Or maybe I'm just stupid... Either way, it works now, so I'm a happy camper.

this is so embarassing. i did the same thing

thanks for the tip foosion

hi,

is it possible to implement multi-channel support for the convolver somehow?
I'm trying to build up an active 4-way speaker system and it would be just perfect
to load 8 different FIR filters...

thanks...

Hi,

I have long time had a problem with visualisations(even build-in ones) skipping every 4 seconds when using Convolver. Is there anything on the Convolver's code that can be causing this behaviour?

I found that setting the playback thread priority on fb2k's advanced options to 3 or lower helps on the issue, but causes skipping when other programs are using cpu-time.

This visualisation skipping has been in every 0.9x foobar2000 I have tried, the last beta included.

Environment: 2.2GHz AMD Athlon XP, 512MB RAM, Windows XP SP2, foobar2000 0.9x, foo_convolve 0.3

Thanks in advance

How are things with crossfeed convolution? That would be so great to experiment with. Or has the development of this component ended?

My interest is in speaker simulation using headphones. I would be happy with symmetrical crossfeed using just one "stereo" impulse response, one channel for left and right direct sound effects and the other for left and right crossfeed effects. I don't think asymmetric true stereo crossfeed effects are that necessary since the ideal listening setting is symmetrical anyway.

Can you recommend me some impulse which makes the sound softer (warmer). I am using Audigy4,KS 24 bit.
