SAM-Audio Models (BF16 Safetensors)
Ungated mirrors of Meta's SAM-Audio model weights, converted to BF16 safetensors format and redistributed under the SAM 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.
