# SAM-Audio Models (BF16 Safetensors)

**Ungated mirrors** of Meta's [SAM-Audio](https://github.com/facebookresearch/sam-audio) model weights, converted to BF16 safetensors format and redistributed under the [SAM License](LICENSE) for easier access.

## What is SAM-Audio?

SAM-Audio (Segment Anything Model for Audio) is Meta AI's foundation model for **isolating any sound in audio** using text, visual, or temporal prompts. It can separate specific sounds from complex audio mixtures.

- **Text prompts** — isolate sounds by describing them (e.g. *"drums"*, *"vocals"*, *"piano"*)
- **Visual prompts** — point at objects in video to extract their sound
- **Span prompts** — specify time ranges where the target sound occurs

The `-tv` variants are optimized for **target correctness** and **visual prompting**.
