多模态联合推理使AudioX的生成质量达到专业水准

2025-08-26 1.2 K

系统的独特优势在于支持视频-文本、图像-音频等多源输入的联合推理。当用户同时提供视频文件和”激昂的进行曲”文本提示时,模型会先通过3D-CNN提取视频中的动作节奏特征,再与文本嵌入向量进行交叉注意力计算,最终生成在节拍和情绪上都与画面同步的音乐。客观评测显示,这种多模态条件下的生成结果,在节奏一致性(beat alignment score)上比单文本输入提升41%,在情绪匹配度(valence-arousal相关系数)上提升29%。专业音频工程师盲测中,83%的生成作品被判断为人类创作,证实了系统已达到商业级质量要求。这种技术特别适合短视频平台自动生成背景音乐等大规模应用场景。
