常见问题
什么是 LUFS，为什么应该使用它？
LUFS（满刻度响度单位）是测量感知响度的行业标准。与简单的音量调整不同，LUFS 标准化确保不同音频文件和平台之间的响度一致。所有主要流媒体服务和广播公司都使用它。
我应该使用什么 LUFS 目标？
播客：-16 LUFS，音乐/Spotify：-14 LUFS，有声书：-18 LUFS，YouTube：-14 到 -16 LUFS，广播：-23 LUFS（EBU R128 标准）。这些目标确保每个平台的最佳响度。
什么是真峰值限幅器？
真峰值限幅器防止音频超过 0 dBTP（分贝真峰值），这可能在格式之间转换时导致失真。提高音量时始终启用它以防止削波。
我可以提高音量而不失真吗？
可以！提高音量时使用真峰值限幅器。它可以防止削波，同时允许您安全地提高响度。但是，极端提升（>10 dB）可能会减少动态范围。
支持哪些文件格式？
我们支持所有常见音频格式：MP3、WAV、FLAC、AAC、M4A、OGG、WMA、AIFF 等。您还可以从视频文件中提取和调整音频音量。
我的音频数据安全吗？
绝对安全！所有音量调整使用 FFmpeg 在您的浏览器本地进行。您的音频文件永远不会离开您的设备或上传到任何服务器。
