# Documentation
|
|
- Class name: SaltAudioInversion
|
|
- Category: SALT/Audio/Process
|
|
- Output node: False
|
|
|
|
SaltAudioInversion节点旨在对音频文件的波形进行反转，实现相位翻转的效果。这一过程可用于创造独特的声音效果或进行音频测试，在某些情况下相位反转可能是必要的。
|
|
|
|
# Input types
|
|
## Required
|
|
- audio
|
|
- audio参数接收一个音频文件作为输入，这是进行相位反转的目标。该输入至关重要，因为它直接影响反转过程的结果，决定了最终音频的特性。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
|
|
# Output types
|
|
- audio
|
|
- 输出是经过相位反转的音频文件，原始音频的相位已被翻转。这可以用于进一步的音频处理或作为音频制作中的一种效果。
