# Documentation
|
|
- Class name: SaltAudioStitcher
|
|
- Category: SALT/Audio/Process
|
|
- Output node: False
|
|
|
|
SaltAudioStitcher节点旨在将两个音频文件拼接在一起，并可选择在它们之间添加静音过渡。它能够通过组合多个音频片段来创造无缝的音频体验。
|
|
|
|
# Input types
|
|
## Required
|
|
- audio_a
|
|
- 要拼接的第一个音频文件。它作为拼接音频输出的起点。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
- audio_b
|
|
- 要拼接的第二个音频文件。它在拼接音频输出中紧随第一个音频文件之后。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
## Optional
|
|
- silent_transition_seconds
|
|
- 在两个音频文件之间插入的静音持续时间（以秒为单位）。这允许在音频片段之间实现平滑过渡或暂停。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
# Output types
|
|
- stitched_audio
|
|
- 将输入音频文件拼接在一起后得到的结果音频文件，可能在音频之间包含静音过渡。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
|
|
|
|
