Part of the allure of the Billie Eilish story isn’t just that she’s a super-talented musical wunderkind. Obviously, that’s a big part…but there’s also the idea that a 14-year-old can record songs and launch a celebrity empire right from her bedroom. Of course, it never hurts to have the right tools on your way to music world domination. Where once it required an engineering studio stacked with engineers at the cost of millions to make real audio magic happen, some brilliant apps have handled audio production power to the masses in ways that would have been exceedingly difficult and expensive even for major stars only 10 years ago. EasySplitter Pro Vocal Remover ($39.99, over 90 percent off, from TNW Deals) is one of those tools, a dazzling little monster of an app that employs cutting edge tech to essentially strip apart a song and use all the pieces your way. As an EasySplitter member, users can log in, upload their song of choice, and hit the button. EasySplitter gets to work, analyzes the song, then carefully peels each element apart, all without ever losing an iota of sound quality. Users can choose between creating two tracks, one for all the song’s vocals and another from all the instrumentation; or an even more granular four track version, with completely separate audio files segmenting vocal, instrumental, drums, and bass tracks.  Using these EasySplitter-created tracks, DJs can conjure their own instrumental music beds and mix music seamlessly. Singers can listen to exactly how a favorite vocalist delivers without the music getting in the way, then record and lay in their own vocals instead. And EasySplitter makes it simple to create karaoke versions of literally any song within seconds. Working for both Android and iOS users, EasySplitter works for everyone from artists, sound engineers, and producers to composers, mixers and more. Audio files get stored in your EasySplitter account and stay there so you can access them anytime. Regularly $599, you can now grab a lifetime subscription to EasySplitter Pro Vocal Remover, which enables users to unravel almost 1,000 songs per year, for over 90 percent off its regular price, down to just $39.99.  Prices are subject to change.
