CapCut normalize voice loudness before music (2026)

2026-09-27 · ~6 min read · CapCut download

Balance narration against background music so mobile viewers do not reach for volume.

CapCut 里对白忽大忽小,多半是 RAW 音量差,不是“降噪没开”。先统一 Loudness,再谈美化。

选中音频轨 → 打开响度/标准化(或 LUFS 相关选项)→ 目标先用 -14 LUFS 试听;短视频平台通常更接近这个区间。

标准化后若齿音刺耳,再轻度去齿音,不要一上来猛拉压缩。压缩过狠会让旁白发糊。

B-roll 环境音单独一轨,比对白低 12–18 dB。不要和人声绑在同一条标准化链路上。

导出前用耳机听一遍开头 3 秒和结尾 CTA;这两段最容易爆音或突然变小声。
