Deezer Launches Vocal Separation Tool Spleeter For Free

Friday, November 8th, 2019 |

Deezer has released a great new AI-powered vocal separation app named Spleeter. The app is open source and free to use for anyone.

Spleeter follows in a line of other signal separation apps that allows the user to split out stems from finished songs. This means that someone can separate the vocals or other parts from the rest of the instrumental.

However, if you think this is just going to be an app where you open it up, upload a song and bang the isolated vocal is on your desktop in seconds, you would be wrong. This requires using your terminal / command line and doing some copying and pasting. They have outlined how to install on GitHub.

The results aren’t perfect, but it rare to find a free app that will be perfect at isolating vocals. Spleeter can split a track into multiple stems up to 100 times faster than real time.

Andy Baio, a mashup scientist, explained how much he loves the new program in a new blog post. He says that the “three models they released already far surpass any available free tool that I know of, and rival commercial plugins and services.” He also provides some examples of audio he has already split up.

The three models are:

– Two stems – Vocals and Other Accompaniment

– Four stems – Vocals, Drums, Bass, Other

– Five stems – Vocals, Drums, Bass, Piano, Other

The difficulty of using this tool will likely prevent loads of copyright infringing mashups, but those who have the ability work with this will have a very valuable application at their disposal. There are plenty of other programs like this out there, but none this powerful and available for free. One reason for that is that most researchers don’t have the catalog to work with like they do at Deezer.

“Here at Deezer, we have access to a fairly large catalog that we’ve been leveraging to build Spleeter. Since we can not share this data, turning it into an accessible tool is a way for us to make our research reproducible by everyone,” Deezer writes.

Winter Music Conference was the cream of the crop of conferences. Every label owner, label A&R, DJ and artist knew they had to go network at the Fontainebleau where the conference was hosted. The conference was not only one of the most important time of the year as it relates to dance music but it was also a place where records were broken and became summer hits. Some of my best DJ memories are from the events I played during WMC in the last 20 years.

I’m so glad to see WMC rebooted with such thoughtful content and first-class curation. It’s been a long time since the industry had a must-do American event and this is it. The reborn WMC!

Winter Music Conference is my ground zero. It has always provided the perfect storm of opportunity and excitement for up and coming artists, including myself back in 2003, where I first caught a glimpse of how it felt to have an audience respond to my work. Over the years, I’ve always made it a point to have WMC in my calendar because that’s the spot where everyone congregates and you can feel it in the air. Creativity, brother and sisterhood, FUN and most of all the chance to come together as a community and celebrate the reason we are all here—the music.”



The Winter Music Conference represents a chance for Beatport to connect directly with our customer community. Having a strong conference means we have a platform to embrace the entire spectrum of electronic music culture. We are proud to support the resurgence of this great event.

I first went to WMC ’87, the year I started Big Beat. It was an incredibly inspiring congregation of indie labels, DJs, artists, songwriters, producers and dance music lovers dedicated to breaking and discovering new music. WMC has been instrumental in furthering the dance and electronic cause; keeping the community connected, vital and relevant, and serving as an amazing springboard for talent. It’s a fantastic crucible for the future of dance music. Long may it live.
