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.

I feel fortunate to have been part of the first-ever WMC. Over the 35 years, it has grown to give us an international forum where we exchange music and ideas. As an attendee and host of many of the award shows, I am proud each time I see new young talent emerge and then become world-renowned. We all have so many Winter Music Conference moments of hearing a seminal breakthrough record for the first time as well as a new DJ with star quality. Magical moments in my career.

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!

Miami has always been a place I’ve considered home and WMC was essential for me and the label in many ways. From showcasing our new music to keeping up with all the new artists and releases. It was the official kickoff of the year and I’m happy to see it thriving again.
