Headphoneus Supremus
The way he mentioned it, I got the impression he was working on it, but Mike is a tough read, and I was multi-tasking so I may have mis-read it.
The dynamic range expansion sounds like something that could be done technologically to me, but I have a hard time seeing it past Mike's filter of doesn't sound like arse. Mike is a vocal opponent of over-compression, so I could easily see it as in "in-joke" of his to have a pop-music de-crapifier filter.
The beat alignment/mis-alignment sounds a bit more like snake oil to me, despite Mike's anecdote about the Rolling Stones. But I wouldn't have believed pitch shifting either, so I'll be happily proven wrong if it's done with Moffat Magic.
Perhaps it's something like what the Chord Mscaler is designed to do ...
