Documentation

• Class name: SaltChangeAudioVolume
• Category: SALT/Audio/Process
• Output node: False

SaltChangeAudioVolume节点用于调整音频文件的音量。它通过指定的分贝数来修改音量级别，可以实现音频信号的放大和衰减。

Input types

Required

• audio
  • audio参数代表要处理的音频文件。它是音量调整的主要输入。
  • Comfy dtype: AUDIO
  • Python dtype: bytes
• volume_decibals
  • volume_decibals参数指定增加或减少音频音量的幅度。正值表示放大声音，负值表示衰减声音。
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• audio
  • 经过音量调整的音频文件。
  • Comfy dtype: AUDIO
  • Python dtype: bytes

Usage tips

• Infra type: CPU
• Common nodes: unknown
