Demix vs Lalal.ai
Both Demix and Lalal.ai help you separate audio, but they answer different questions: Demix is built for natural-language prompts ("extract the sound I describe"), while Lalal.ai is built for predefined stem categories ("extract vocals/drums/etc").
- Choose Demix when you want to isolate a specific sound that you can describe (a synth pad, a texture layer, crowd noise, vinyl crackle, reverb tails).
- Choose Lalal.ai when you only need standard stems from the available stem types (like vocals or drums).
Side-by-side comparison
| Dimension | Demix | Lalal.ai |
|---|---|---|
| How you specify what to extract | Type a natural-language prompt | Select from available stem categories |
| Best at | Isolating the sound you describe (prompt-driven) | Separating predefined stem types (category-driven) |
| Outputs | Isolated stem + residual track (everything else) | Separated stem(s) for the selected type(s) |
| When to use it | Sampling, remixes, sound design, extracting specific layers | Quick standard stems for common workflows |
Prompt examples Demix is built for
These are the kinds of requests where natural-language separation is especially useful:
| Goal | Example prompt |
|---|---|
| Isolate a specific vocal character | lead vocals with reverb |
| Extract a texture layer | vinyl crackle |
| Pull out a background layer | background synth pad |
| Remove ambience from a mix | crowd noise |
| Get the spatial tail | reverb tails |

Frequently Asked Questions
What is the main difference between Demix and Lalal.ai?
Demix is prompt-based: you describe the sound you want to extract in natural language. Lalal.ai is a traditional stem splitter: you pick from the stem types it offers (for example, vocals or drums) and it separates those categories.
Is Demix just a vocal remover?
No. Demix can isolate vocals, but it's designed to extract any sound you can describe — including specific instruments, textures, and effects layers — using a natural-language prompt.
What files does Demix output?
Each extraction produces two files: (1) an isolated stem that matches your prompt, and (2) a residual track that contains everything else.
Which tool is better for sampling and sound design?
If you're trying to pull out a specific layer (for example, a synth pad, vinyl crackle, or crowd noise), Demix is built for that prompt-driven workflow. If you only need standard stems like vocals or drums, a traditional stem splitter may be enough.
Does Demix store my audio?
Uploads are automatically deleted within 24 hours. Extracted stems are available for download for up to 7 days.
