跟混音响度有关系,见:音量标准化和在线视频网站的电平
懒得调音量的话,用 mpv 解决办法是自己挂个滤镜实现音量标准化
我的参数类似是 youtube 的目标 -14 LUFS 动态音量标准化,理所当然会压缩动态
- af-append = loudnorm:I=-14:LRA=11:TP=-1
复制代码
音频的响度级别可以用 ffmpeg 测
- ffmpeg -i '[AI-Raws] 戦闘員、派遣します! #01 (BD HEVC 1920x1080 yuv444p10le FLAC)[CBA62B00].flac' \
- -filter_complex ebur128 \
- -f null -
复制代码- Integrated loudness:
- I: -17.7 LUFS
- Threshold: -28.4 LUFS
- Loudness range:
- LRA: 11.1 LU
- Threshold: -38.4 LUFS
- LRA low: -24.1 LUFS
- LRA high: -13.0 LUFS
复制代码
因为懒得调音量,我也用 easyeffects 挂了 autogain 滤镜
顺带挂个低音增强提升听感(原理)
虽然质量感觉不如 mpv 里挂滤镜,但也还凑合
