Stable Audio 3 让音频生成门槛大幅降低——小型模型在普通笔记本上就能跑，做游戏音效、短视频配乐的创作者可以直接上手试试。
Stability AI 发布了 Stable Audio 3，一个用于乐器音乐和音效生成的潜在扩散模型家族。该版本包含小型和中等变体的开源权重。小型模型可在 MacBook Pro M4 CPU 上运行，中等模型适配 8GB VRAM 的消费级 GPU。两者均通过三阶段训练流程（流匹配、蒸馏预热、对抗后训练）生成 44.1 kHz 立体声音频。在 BBC 音效基准测试中，SA3 中等模型在 5 秒片段上取得 FAD 0.369 的分数，低于论文中评估的所有开源基线。
Stability AI Releases Stable Audio 3: A Family of Fast Latent Diffusion Models for Audio Generation and Editing
Stability AI has released Stable Audio 3, a family of latent diffusion models for instrumental music and sound effects generation. The release includes open weights for the small and medium variants. Small runs on a MacBook Pro M4 CPU. Medium fits on consumer GPUs with 8 GB of VRAM. Both generate stereo audio at 44.1 kHz using a three-stage training pipeline: flow matching, distillation warmup, and adversarial post-training. On the BBC Sound Effects benchmark at 5 seconds, SA3 medium scores FAD 0.369 — lower than every open-weight baseline evaluated in the paper.
