By default yes — a 48 kHz audio track in WebM becomes 48 kHz in AIFF. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options include a sample-rate dropdown.
我能从多个 WebM 文件提取音频到 AIFF 的批量吗?
+
Yes — drop a folder of WebM 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.
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour WebM → AIFF finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the WebM audio as AIFF?
