Open-source SepGen LoRA gives LTX-2.5 videos a separate audio track for every sound

Developers released SepGen, an open LoRA for LTX-2.5 22B dev that outputs an individual audio track per captioned sound in the same generation run — prompt "a jeep, its engine growling" and "a taxi, its horn honking" and you get the video, the full mix, and each sound isolated on its own track. The same weights can also separate sounds from existing videos, enabling spatial-audio walkthroughs. Two LoRAs, code and training configs are open-sourced on GitHub and Hugging Face, and the work is featured on HF Daily Papers.
