- 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
