Bring Back Central Channel Extractor
The Center Channel Extractor is very important to be able to separate out vocals from background sound or music. However, I found after uploading a file, it did not operate as the tutorial explained here: https://helpx.adobe.com/audition/how-to/remove-vocals-background-music.html
The Central Channel Extractor would run but show an error about CPU and latency loading issues. It would have no option for previews of changes via the CCE and lacked an Apply button on the popup menu. In addition, even after using the Effects panel to press "Apply" to get around the lack of buttons on the CCE popup menu...all the effects selected in CCE were not applied.
At this point in time, it does not appear the vocal remover, Acapella or other useful options in CCE are working. I would like to request those features are somehow returned as they are very helpful.
I found this website here very helpful, if Adobe Audition can find a way to mimic the AI technology used here and the ease of use of the UI it would be enormously helpful.

We’re unable to see any difference in behavior in the CCE effect, or from your screenshots. The pop up about CPU and latency is a warning, not an error, and can be disabled by checking the box on the dialog if your system is capable of rendering it during real-time playback.
Most of the presets default to use “Center” as the Extract mode, which disables most of the parameters which are used to customize the position of the affected audio in the stereo field. You can change this option to Custom to unlock all the parameters and adjust them as desired.
There are certainly some exciting new advanced in AI and machine learning technologies around isolating different components in a recording. CCE is based on DSP that was developed for isolating elements in a mix based on the content in a specific region of the stereo field. Many of the newer models utilize Source Separation, a technique of identifying content in other ways, and Audition does present this technology in one effect, Sound Remover, that can be used to remove or minimize elements of a recording – similar to Noise Reduction, but focused more on foreground and repeating sounds than general background ambience.
If adjusting the “Extract” parameter to Custom doesn’t unlock the parameters you are expecting to see, please update and let us know more details. As Matt has requested, a screen capture video is EXCEPTIONALLY useful for troubleshoot and better understanding some issues.

"CCE workflow did not function through the Effects Rack anymore." I am looking at it, it is working for me. You should to provide video showing it not working, a screen recording.
I also reviewed the video, it also is correct still. The video is not showing the Center Channel Extractor being used outside of the Effects Rack (again, at 50 second in the video you cleary see Jason launch the effect via "Effects>Stereo Imagery>Center Channel Extractor..." and NOT via Effects Rack. So stating repeatedly that the tutorial is launching the via the Effect Rack, and there for wrong, is puzzling. The tutorial is fine from what I can tell. Please, if I am mistaken, point to exactly in the video where it is incorrect.
In the last screen shot you posted, you have the effect open via the Effects Rack, and the Effect Rack set to the Process; Entire File. In this mode the effect will be active on all of the audio, regardless of selection. The default behavior is "Selection Only" which is more similar to launching the effect outside of the Effects Rack, similar to Jasons tutorial.
Also, the Center Channel Extractor is pretty unique in that it works only on specific types of audio. Music is what is was designed to work on, if you run it on a mono clip nothing will happen. Again, a video from you will showing how it isn't working will help clear up any confusion here.
When launching any effect via the Effects Rack, the UI is different than launching it outside of the Effects Rack. When launched from the Effects Rack, there is no transport control UI in the effect window.
Please, instead of us going back and forth ad nauseam, post a video showing what is not working so I can see exactly what istt' working for you.

@ Matt,
When someone tries to access the Central Channel Extractor through Effects Rack like in the video, it does not work. It also did not work for the supervisor who attempted to get it to work remotely. As you can see the preview button is missing in the pop-up menu as it occurs in the video and it also does not you to apply any changes directly in the pop up menu from the Effects Rack.
So, the video is incorrect and needs to be updated. The issue is Adobe Audition program no longer operates the way it does in the video and so the video needs to be updated to reflect how the program actually functions.
The CCE workflow did not function through the Effects Rack anymore.

"With all due respect, I followed the work flow exactly as in the Adobe Tutorial where the individual accessed the Central Channel Extractor through the Effects Rack --> Stereo Imagery --> Central Channel Extractor and it led directly to him being able to have the floating effects panel offer the preview option and the Apply button directly in the pop-up menu. If that is no longer the case and that is not working in the software any more, that tutorial video should be removed and updated."
At 50 seconds into the video that is exactly what he does. I don't see that the video is incorrect at all.

I tested your alternative and it worked, thank you for correcting the guidance as it resolved the issue.
With all due respect, I followed the work flow exactly as in the Adobe Tutorial where the individual accessed the Central Channel Extractor through the Effects Rack --> Stereo Imagery --> Central Channel Extractor and it led directly to him being able to have the floating effects panel offer the preview option and the Apply button directly in the pop-up menu. If that is no longer the case and that is not working in the software any more, that tutorial video should be removed and updated.
In addition, the Adobe representatives, including up to the supervisor of the technical team spent almost 45 minutes accessing my computer remotely and tried various ways to solve it. He could not figure it out and told me there was no way to work with the Central Channel Extractor feature at this time. That it was not working in Adobe Audition.
I think Adobe Technical Assistance staff helping people in the chat windows should be trained on this feature so they are not providing misinformation to people who contact them regarding issues with the outdated tutorial.
They should have been the ones to tell me about the alternative way to use that feature, I kept asking them if there was a way to fix the issue and they kept adamantly saying "No", there was no way around the Central Channel Extractor not working at this time. I recommend further training for Adobe employees and the Quality Assurance team address that response.

I am part of the team that makes Audition, the Center Channel Extractor has not been removed or altered for quite some time. The person on the phone was simply mistaken.
By looking at your screen shot it appears that you are trying to use the Center Channel Extractor effect via the Effects Rack, that is why there are missing the "Apply" button. When launching the effects via the Effects Rack, the Apply button is in the bottom portions of the Effects Rack panel, not in the floating effects panel UI.
To see the play, loop, and Apply button (like shown in a large portion of Jasons tutorial) you will need to launch the effect from the menu: "Effects>Stereo Imagery>Center Channel Extractor...", not via the Effects Rack.
"Central Channel Extractor would run but show an error about CPU and latency loading issues". This warning is just to tell you that the effect will use more CPU or have a higher latency than other effects in Audition. This is perfectly normal and you will only see this described if the effect is launched via the Effects Rack. If the effect is launched via the menu item as I described above, there is no warning.
If the warning is causing issue, you can simply put a check next to the option "Don't show this alert again". This will suppress that warning dialog in the future.

@Matt Stegner:
I talked to the Adobe Audition chat representatives twice and they both told me this feature is down in Adobe Audition. They said it currently is not working because there is a bug that has not been fixed but they would put in for a feature request.
I asked several times if there were other ways to extract vocals and they said, "No", not at this time. They specifically said the Central Channel Extractor in Adobe Audition is not working period. Why would the experts who design and maintain this software say that twice up to the level of the supervisor?
The loading error is implied because of the difficulty of audition in handling the CPU memory, it does not allow the preview to run in the pop-up window or to apply the effects. I don't mind you asking me what I meant to say, but there is a reason why I shared that information.

"Bring Back Central Channel Extractor"
The center channel extractor has not been altered and is still fully functional. Your screen shot implies are accessing it via the Effects Rack, which functions differently than via the effects menu.
Jason's video (which you linked above) covers this at 38 second mark."an error about CPU and latency loading issues"
The dialog is warning that the effect will use high amounts of the CPU and may not playback in realtime. It mentions nothing about a loading error.
