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.
