StemRoller

Attempting to separate a song's musical elements isn't the easiest job in the world, and it's one of the many things that separates good music producers from great ones. Even if you're just starting out, attempting to sample certain parts of a track into your new song can prove to be quite challenging, and it starts with separating the vocals and instruments.

Having a dedicated tool do all of that for you sounds convenient, and for the most part, it is. StemRoller is a tool that can extract vocals, drums, bass, and other such instrumentals from your songs, without requiring much input from you.

The tool is as close to automatic as they get, essentially. You'll first have to look up your song, and for this, the YouTube integration comes in very handy. After finding the track of your choosing, click Split, and let the software work its magic.

As for the magic, it can take a while to manifest. Upon clicking Split, the program will start processing your chosen song, and depending on your hardware, this can take quite some time. On our 11-th gen i7 machine, demixing a 5-minute song took just a little over 10 minutes. Of course, it should be mentioned that the tool also uses a significant amount of system resources during the process, so plan accordingly.

Upon finishing the demixing process, the program will automatically open a folder that contains your song's extracted parts. Separate files are created for all the instruments, such as for the drums and bass, as well as for the vocals.

It's worth noting that the size of the extracted files isn't at all insignificant: about 300 megabytes' worth of data for a 5-minute song, in our case.

StemRoller works rather well, though the time it takes for the algorithm to do its thing could be improved upon. Nevertheless, for the patient ones out there, the results are up to the task, so at least you get a good sample in the end.
