# Documentation
|
|
- Class name: SaltAudioTrim
|
|
- Category: SALT/Audio/Process
|
|
- Output node: False
|
|
|
|
SaltAudioTrim节点旨在将音频文件修剪到指定的起始和结束时间，从而精确控制感兴趣的音频片段。
|
|
|
|
# Input types
|
|
## Required
|
|
- audio
|
|
- 待修剪的原始音频数据。这是操作的主要输入，决定了要处理的音频片段。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
- start_time_seconds
|
|
- 音频应该开始的起始时间（以秒为单位）。此参数设置要保留的音频片段的起始点。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- end_time_seconds
|
|
- 音频应该停止的结束时间（以秒为单位）。此参数定义要保留的音频片段的结束点，有效地修剪音频。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
# Output types
|
|
- audio
|
|
- 修剪后的音频数据，以字节流的形式返回。这个输出代表了指定起始和结束时间之间的音频片段。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
