Yes — drop a folder of MP4 files in and we extract audio in parallel. Premium users get more parallel workers; on a 50-file batch this is the difference between 90 seconds and 8 minutes.
是否要用标题 / 艺人 / 专辑标记 AMR 文件?
+
如果 MP4 文件有章节或流流元数据, 我们将艺人 / 标题/ 相册字段复制到 AMR 容器中。 否则, AMR 文件没有标记, 如果您需要更丰富的标签, 请使用标签编辑器 (Mp3tag, Picard) 后导 。
从 MP4 文件提取 AMR 需要多长时间?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour MP4 → AMR finishes in 3-9 minutes on the standard pipeline.
