it can be traded as it is, it is not lossy.

the track you provided does not have a single place to take a noise sample from, there is music all the way through!

the main problem of the noise is the buzzing sound, this cannot be tacked with normal noise reduction.

the buzzing comes from the red vertical "posts" visible in spectral view (pictured below). I have a method to safely eliminate this, but each and every one would have to be done manually there is no way to automate it. if you really love this show, you could give it a try but it would most likely take minimum a year of your time depending on how long the total show is to eliminate each "red post" individually!
