用程序生成音效，实测在科幻片中表现可信，动画片日常音效仍需优化。
Sound effects in media:A comparative analysis of recorded and synthetic samples in live-action and animation
- 用在线程序引擎生成音效，与真人和动画画面匹配测试。
- 科幻类场景中激光、爆炸等音效感知真实度超80%。
- 动画片日常动作音效可信度低，需改进特定声学特征。
为影视、游戏等叙事作品制作音效对营造环境至关重要。传统方法依赖重复录制实物或使用音效库，耗时且单调。为解决此问题，本文采用程序化音频（procedural audio）技术，通过在线引擎快速生成音效样本，并将其与真人实拍及动画画面融合测试。结果表明，该方法在戏剧与科幻类场景中表现优异，尤其对激光、撞击、气流和火箭等音效具有高度可信度；但在卡通类作品中，模拟日常动作的合成音效可信度较低。研究还收集音频专家反馈，识别出需优化的具体音效模型及关键音频特征。
原文摘要 · Abstract (English)
Creating sound for storytelling is crucial to establishing the environment in productions such as films, TV series and video games. This process often involves repeating, layering and recording real objects or using sound libraries, which can be time-consuming and repetitive. To address these challenges, procedural audio, also known as digital foley, offers a solution by allowing sound designers to quickly generate samples. Despite its efficiency, questions remain about the believability of synthetic samples compared to real ones. In our study, we compared synthetic samples generated by an online procedural engine and integrated them with both animated and live-action visuals. Our results indicate that procedural audio is highly effective and perceived as believable in drama and sci-fi scenes, particularly for sound models such as lasers, hits, air and rockets, whereas synthetic sounds weren't as believable in cartoon productions when representing everyday actions. Finally, we identified specific models that needed optimisation and highlighted audio features that needed improvement with feedback from audio professionals.
