Annotated screenshot indicating the effects and their issues

When searching for (audio) "Channel" effects, you get two "Copy Channel" effects, one in the Audio category, the other under the Audio channels category. The "Copy Channel" effect, under the Audio category, when active does the same as the "Swap Channels" effect in the Audio channels category.

Also, the Remap Channels effect seems to have no effect. Both the "Copy Channels" and "Swap channels" under the Audio channels category seem to be working fine.

Remaps channel has been removed as it doesn't work. But this needs a fix:

"Copy channel" under audio add "channelswap" 
"Channel swap" adds "swapchannel"
"Copy channel" under audio correction adds "channelcopy"

So as far as I see
"Copy channel" simply appears twice but in fact adds the "channelcopy" effect.

So the fix would be to remove one? What else needs to be fixed?

One adds channelcopy but the other adds channelswap as shown in terminal. So we need to see what id the difference of those and which one works better.

And decide what to keep.
