Bro the original is in 435 hz not in 440 hz so I tune the guitar in 435 and everything fine till the min 4:22 when the harmony start, it doesnt sound tooo good in 435 hz but neither in 440 hz, do you know the exact hz? Also the digital tuner which Im using is very especific with the cents, so you can move one by one for example 435.1 435.2 etc... otherwise nice track
As he said, he recorded that, but normal isolating is just "filtering" the right pitch, you can do it also on audacity, but isolating have got one problem, when some instruments have some pitch, like there kirk and james, its imposible. But its great for isolating drums, sometimes vocal. But the worst and annoying thing on in is that when you filter it too much, it will sound like plastic, and when you filter it less, some sounds from background might be there. But i belive there is some kind of programs with artificial intelligence and can know what to filter. 😀 Hope that was helpful, but I wrote off after a year, so maybe all right :D
