Quick facts about Lalal.ai
Lalal.ai stands out as one of the few online stem separation services not built on older Spleeter technology. It has its own proprietary AI engine, allowing it to achieve better separations than many 2020-era tools. However, it remains a closed-source solution, so details on its architecture and performance metrics are limited.
Lalal.ai’s comparison to older Demucs (v3)
In its own marketing, Lalal.ai compares favorably to Demucs v3. But the Demucs ecosystem has advanced rapidly:
- Demucs v4 includes architectural improvements and training updates.
- Ensemble strategies from the 2023 Sound Demixing Challenge further boost quality in complex scenarios.
Music Demixer proudly integrates Demucs v4 (and beyond) for near state-of-the-art separation without the restrictions of a proprietary “black box” AI.

What makes Music Demixer stand out?
1. Fully updated Demucs v4 model
-
Cutting-edge AI With each major release, Demucs has significantly improved separation quality. By using Demucs v4 and custom ensemble mixing, we deliver highly accurate stems, especially in scenarios with complex overlaps of instruments and vocals.
-
Transparent & open heritage Demucs is rooted in academic research from Meta, Spotify, and community contributions. We proudly share our reliance on these sources. Lalal.ai, while advanced, is private about its AI infrastructure.

- PRO plan For just $50 CAD per year or $10 CAD per month, gain unlimited access and advanced features - like integrated MIDI conversion and sheet music transcription - at a fraction of the cost of some major commercial tools.
While many praise Lalal.ai’s performance, some users prefer alternatives when it comes to cost, support, or user experience. We believe healthy competition benefits all creators, and are confident that Music Demixer is a strong contender — give us a try and we may surprise you!

1. Is Music Demixer free to try?
Yes. Our free tier lets you discover how Demucs v4 handles your music. Upgrade to PRO for unlimited usage and extra features like MIDI and sheet music transcription.

Not necessarily. Thanks to WebAssembly, modern browsers can utilize CPU and GPU acceleration for performance comparable to many cloud solutions. And you won’t be stuck waiting in server queues.

4. Why not just trust Lalal.ai’s custom engine?
Lalal.ai is indeed advanced, but if you prefer a transparent, open-research approach—or you want local processing for privacy—Demucs v4 via Music Demixer might be better suited to your needs. Some users also find Lalal.ai’s credit-based pricing limiting.
