Music Demixer vs. Ezstems.com: which stem separation tool is best?
Our site, Music Demixer (aka https://freemusicdemixer.com), uses the cutting-edge Demucs AI model to separate music into stems. In this article, we’ll compare Music Demixer to ezstems.com, a cloud-based service that uses Spleeter to separate music tracks.
Check out our previous article on Spleeter vs. Demucs for a detailed comparison of the two AI models.
Introduction to Ezstems.com
Ezstems.com has gained some attention for offering 4- and 5-stem separation along with an optional MIDI converter. However, there are some important differences in quality, reliability, cost, and privacy. We believe that Music Demixer, powered by advanced AI research from companies like Meta and Spotify, is a stronger choice for most creators. Below, we’ll explain why.

Quick overview of Ezstems.com
Spleeter-based core:
- Limited to 4/5 stems
- Relies on the open-source Spleeter library, originally developed by Deezer in 2020. While Spleeter was groundbreaking at launch, it lacks many modern refinements and advanced architectures that newer AI models (like Demucs) bring to the table.
Cloud-based with potential drawbacks
- Uploads to remote servers
- Your audio files are uploaded for processing, which may raise privacy concerns if you’re working on confidential or unreleased tracks.
- Uncertain reliability
- Some users have reported issues where the processing gets stuck indefinitely without clear updates, making it difficult to plan your workflow.
Customer experience reports
- Customer support challenges
- According to some users, customer service responses can be delayed or absent. If your audio processing stalls, there may be no quick fix or reliable guidance from the support team.
