There is this song that I want to remove the watermark from (Yeah I know you're gonna give me a disclaimer about your lack of responsibility if I violate copyright, but I know that already and am not planning on distributing the song, and before you say "just buy it" note that it is a production track that costs $50). I have found out that the watermark is entirely on the center channel. I have tried making the track mono, and it did remove the watermark, but it sounds awful in mono because of how the track was mixed, so I want to have it in stereo, minus the center track. I tried a lot of different things, such as inverting the left and muting the right then setting back to stereo, then adding in another copy of the track and muting the left to leave just the right, and a lot of other similar things, but none have worked so far. If someone could tell me how to remove the center track while leaving it in stereo that would be greatly appreciated.

If you want to hear the original song here is a link to the premiumbeats page: https://www.premiumbeat.com/royalty-free-tracks/restless

Also, not sure if anyone would be willing to do this, but I bet if you have a software such a melodyne you could probably remove the watermark in 10-15 min.

Thanks!

    There is no such thing as a center channel. Everything that appears to come from the center is equally in both channels. Regardless of whether anyone here supports or opposes piracy, questions about defeating copy protection are off-topic here. Frankly, that track isn't so great or complicated and it's probably easier to make up your own beat. – Todd Wilcox Jan 20 '18 at 4:39

    I'm voting to close this question as off-topic because Stack Exchange is based in the US and assisting in defeating copy protection could be a violation of the Digital Millennium Copyright Act. – Todd Wilcox Jan 20 '18 at 4:42
  • @ToddWilcox "copy protection" is not what we have here. "Watermarking" does not prevent copying, it merely helps to determine the source of a copy. DMCA should not apply here, standard copyright at most. – Ye Dawg Jan 20 '18 at 18:25
  • @YeDawg "CMI is protected by the DMCA from alteration by distributors or users... ... the legislative history repeatedly refers to digital watermarks as CMI, and they can be used to preserve identification of the source of the work."

I have previously referred to this as "The holy grail of the misinformed".

It cannot be done. You cannot un-bake a cake.

You may have some small success at removing/isolating anything in the centre by phase-reversing the two sides... but then, of course, you have the sides out of phase, which is to say the least, uncomfortable to listen to.

Pay the money to use the track.

As has been said in comments, there is no "centre track". It's stereo - the reason anything sounds like it comes from the centre is it is equal loudness in both sides.
That's why the phase-invert trick works, it cancels out one side against the other... though it usually sounds horrible & will at the same time remove anything else panned to the centre.
