- Uploading a video file too large for the browser (keep it under 2 GB).
- Closing the tab before processing finishes: the conversion stops.
- Using an exotic input format (prefer MP4, WebM, MOV, AVI).
- Picking a bitrate so low that quality drops noticeably.
专业技巧
- Pick H.264 (MP4) for the widest compatibility.
- For the web, use WebM (VP9/AV1): smaller file at the same quality.
- Keep the original: processing is local but the download is final.
- On mobile, plug in the charger for long videos.

常见问题
为获得最佳质量，应选择哪种音频格式？
WAV提供无损质量但文件大。MP3（320kbps）是质量/大小的绝佳折衷。Apple推荐AAC。
我可以从YouTube视频中提取音频吗？
我们的工具只处理本地文件。请先合法下载YouTube视频，然后使用我们的音频提取工具。
音频提取会保留原始质量吗？
是的，如果可能，我们会在不重新编码的情况下提取音轨。对于WAV，质量与原始文件完全相同。
音频提取需要多长时间？
提取速度非常快：1分钟视频≈5秒处理。比视频转换更快。
