I'm trying to find an effects plug-in that will accept a stereo signal and eliminate all right-panned sounds from that stereo signal while retaining everything from the center to the left.

I know there are various programs that can eliminate center-panned sounds, particularly in the effort of removing vocals.

I've tried Waves S1-Imager, unfortunately that can't get the job done any way I've tried it.

Thx.

Ok, to simplify.... I want to pan side-oriented sounds without affecting the position of center sounds.

What you need is Kingston's up and coming new technology. There was a thread about that here somewhere. AFAIK there are no plugins/effects out there right now that can remove the side information and leave the center without some serious artefacts.

Ah

I've tried plug-ins that claimed they can pan left/right individually from eachother. Unless I misunderstood the idea, it turned out to be a load of bs.

Thanks for the info. Do you have a link to this upcoming Kingston gadget?

Try C_SuperStereo out in the meantime - it'll take the right side out, you can still find it in a few places...I'm using it right now for a botched "stereo" board mix.

I'm very interested in the new Kingston thing whenever it comes out. I always like to have 2 (or more - hehe) plugs that do the same thing...

If you got ParEQ3 while it was available, just set monitoring to Side.

I'm sure Voxengo has a free plug for M/S stuff like this.

Otherwise - just do it the hard way. Clone your track and invert the phase of one. The information that is common to both (The Mid or Dry stuff) will cancel out, and the Difference (Side stereo ambiant stuff) will remain.

Create the Mid stuff by Summing Left and Right - in other words just convert to mono. The centre dry stuff gets boosted 6dB (which you need to cut to avoid clipping). The side stuff doesn't get this boost, so is effectively lowered by 6dB (or 12dB by the time you've adjusted for clipping).

Combine and mix to taste.

erm....when something is hard left-panned, just use only the right channel and make it mono, there you go? or am i totally wrong here?

Why do it the easy way?

Thanks, but I don't think this can do what I want.

It can remove one side, but at the same time it moves the opposite side to the center. I want to remove one side without affecting the other, or likewise move one side to the center without removing the opposite side.

If all else fails - convert your stereo file into the four possible mono streams:

Left, Right, Mid and Side. Mid is the mono'd left and right, Side is the mono'd left and right with one of them inverted.

Then - using these in a mixer, combine and pan them to taste. If there is something that you would rather remove than add, invert the phase and mix it against the track that contain this, using the same pan position.

If it can't be done that way, it probably can't be done.

You might be luck and be able to selectively boost or cut some things with eq.

...get Voxengos M/S plugin, remove the mid from a cloned track and pan...as long as we're giving options

Tried the M/S method before, even tried ParEQ3, but not what I'm looking for either.

It can remove one side, but once again this comes at the cost of forcing the opposite side to the center.

Uhm.

#1, when something is hard left panned, there is no right channel.

#2, I don't want to make it mono.

My little mind can't comprehend whether that will do what I'd want it to, but given that I've tried a wide load of options, I'm not sure it's worth all the effort to try. Particularly when this has to be done solely with effects plug-ins.

Remarkable how complicated it can be.

Did anyone ever use S1-Imager? Ultimately what I'm trying to achieve is to narrow the width of the left channel only while keeping the right as is. The imager however as all other stereo width plug-ins I've seen reduce the width of both sides, but are unable to do it for one individually.

Try using C_SuperStereo to decrease the percentage of the Left channel and increase the percentage of the Right channel while leaving the center intact:
