SAM Audio
Promptable audio separation for speech, music, and sound effects.
SAM Audio is a clever research-grade tool for promptable separation, but its lack of API and commercial support limits it to prototyping. If you want a free, flexible way to isolate audio with text or clicks, it's worth a spin. For production, commercial alternatives like iZotope RX or Acon Digital offer better support and reliability.

About SAM Audio
SAM Audio is an open-source AI model from Meta FAIR that separates any sound from a mixed source using natural language, visual clicks on video, or time spans. It lets you isolate specific audio components—like a dog barking, a guitar track, or a person's voice—by describing what you want, clicking on the visual element in a video, or specifying a time range. This approach unifies speech, music, and sound-effect separation into one promptable framework, making it a versatile tool for audio engineers, video editors, researchers, and content creators who need precise control without complex setups. The model's promptable architecture offers flexible and intuitive control, so even non-experts can achieve granular separation. It supports text prompts (e.g., "dog barking"), visual segmentation in videos, and temporal boundaries to isolate specific audio components. Because it's a single model, you don't need separate tools for different types of audio—just prompt and separate. This accessibility is a key advantage for quick edits and creative exploration. SAM Audio is open-source, with pretrained weights and inference code available on GitHub and Hugging Face. This makes it free for research use, though there's no official API or commercial support. It currently handles single-channel audio and requires a GPU for fast inference. For researchers and developers, the open-source nature means it can be adapted and integrated into larger projects, while the Hugging Face integration simplifies downloads and deployment. Compared to commercial separation tools that often focus on a single domain (like voice-only or music-only), SAM Audio's unified, multi-domain approach is a differentiator. It's ideal for prototyping and academic work, but production users should look elsewhere for enterprise-grade support and licensing clarity.
Behind the Verdict
SAM Audio stands out for its unified promptable design, letting you separate speech, music, and sound effects with a single model. The ability to click on a video frame to isolate a sound is a standout feature that few competitors offer. For researchers and hobbyists, the open-source availability and Hugging Face integration mean you can experiment at no cost. However, the lack of an official API and commercial support makes it a poor fit for production applications. You'll need to handle your own GPU inference and licensing review. If you're a developer building a product, commercial alternatives like iZotope RX or Acon Digital provide stability and support. For creative pros, it's a great tool for quick edits and exploration, but don't rely on it for mission-critical work.

Real-world workflow fit
Concrete scenarios for the personas SAM Audio actually fits — and what changes day-one when you adopt it.
Isolate a guitar track from a mixed song using a text prompt like 'electric guitar' and export the stem for remixing.
Outcome: Within minutes, you get a clean guitar stem ready for processing, saving hours of manual audio editing.
Click on a dog barking in a video frame to isolate its sound, then remove it from the scene while preserving other audio.
Outcome: You can quickly clean location audio without losing important dialogue or effects, speeding up the editing workflow.
Use SAM Audio to separate bird calls from noisy field recordings for wildlife analysis.
Outcome: You gain a flexible, reproducible separation tool for your research, all at zero cost and with full code access.
Use Cases
- Isolate a specific conversation from a crowded restaurant recording using a text prompt.
- Separate a guitar track from a song by clicking on the guitar in a video.
- Extract a dog barking sound effect from a street recording with time-span selection.
- Remove background noise from a podcast by describing the desired speech prompt.
- Clean up audio for video editing by visually clicking on unwanted sounds.
- Analyze wildlife recordings by prompting for bird calls.
Models Under the Hood

Limitations
- SAM Audio is a research model with no official API or commercial support.
- It requires significant computational resources for inference (GPU recommended).
- The model currently only accepts single-channel audio and may struggle with highly overlapping sources.
- License is research-focused, so commercial use requires careful legal review.

Featured Head-to-Head Comparisons
Sam Audio vs Splice
If you need a vast library of royalty-free samples and rent-to-own plugins, Splice's monthly plans (starting at $4.99) are unmatched. But if you require precise, prompt-based audio separation for speech or effects, SAM Audio's free, open-source model is a powerful, cost-free alternative. Choose based on your core workflow: sample sourcing vs. source isolation.
Sam Audio vs Landr Mastering
LANDR and SAM Audio serve completely different purposes: LANDR is for mastering finished tracks, SAM Audio for separating mixed audio. Pick LANDR if you need a quick, AI-powered master with reference matching and album cohesion (starting at $10/track). Choose SAM Audio if you need to isolate speech, music, or effects from a single audio file — it's free and open-source but requires technical setup.
Sam Audio vs Storyfile
For museums or legacy projects needing authentic interactive human avatars, StoryFile is the clear choice. For audio professionals who need to separate sounds with simple prompts, SAM Audio is free and state-of-the-art. They solve entirely different problems, so your decision hinges on whether you need conversational video AI or audio source separation.
