我能从多个 AVI 文件提取音频到 MP3 的批量吗?
+
Yes — drop a folder of AVI files and we extract audio in parallel. Premium users get more parallel workers; on a 50-file batch this is the difference between a couple of minutes and ten-plus minutes.
Will the MP3 be tagged with title / artist / album metadata?
Audio demux + encode is fast — typically 5 to 15% of the source duration. A 1-hour AVI → MP3 finishes in roughly 3 to 9 minutes on the standard pipeline; Premium parallelism cuts this further for batch jobs.
Can I extract just a section of the AVI audio as MP3?
