MOSS Audio

MOSS-Audio is a modular audio foundation model family for unified real-world audio understanding rather than just transcription. The repository says it combines a dedicated audio encoder, a modality adapter, and a Qwen3 language-model backbone, with cross-layer feature injection and explicit time-marker insertion for stronger temporal reasoning. It supports ASR with timestamps, speaker and emotion analysis, sound-scene understanding, music understanding, audio QA, summarization, and complex reasoning. The initial release includes 4B and 8B Instruct and Thinking variants, with the 8B-Thinking model reported as the strongest open-source model on the repoโ€™s general audio-understanding benchmark summary.
