A few weeks ago, a company named Deezer released spleeter: free, open-source artificial intelligence-based software that can split an audio recording of a band into separate instruments, including vocals.
Here is their press release.
You need a relatively modern computer, with an Intel chip that supports some version of AVX.
If your computer doesn't support the required features, there is a free, online web-based version of spleeter you can try.
I managed to get it installed on one of my computers. It's not easily done, but I can give more details of how to do it if anyone is interested.
I've attached an example of what it can do. I had it extract the vocals of Bob Dylan singing Leopard Skin Pillbox Hat.

"Relatively modern" means something different to different audiences. Fairly proportional to your age, generally. So to spell this out:
AVX was introduced in 2011 (Q1 for Intel, Q3 for AMD). Codename for the Intel's first CPU with AVX is "Sandy Bridge" and AMD's first is "Jaguar".
A more marketing-friendly name for the Intel "Sandy Bridge" would be Intel Core i3/i5/i7 2nd Generation. And the full marketing name for one example CPU of this generation would be "Core i7 2600".
As of today, Intel is on the 10th generation - so there are "lots" of generations of past Intel chips that support AVX. If your PC is running Win 10 - then you should be fine.
I can't speak to Mac specifics. Macs manufactured in 2011 or later would all support AVX.

I can confirm that Spleeter works in CPU mode on my AMD Ryzen 7, so Intel is not a requirement.
It's worth noting that Spleeter can also be run on the GPU (being that it is a neural network), which should work regardless of your CPU and will be noticeably faster especially if you have an older (but still supported) CPU. This requires a CUDA-capable Nvidia GPU with a compute capability of 3.0 or higher (roughly speaking, anything from a GTX 650 onward).
