VHS_LoadAudioUpload节点用于在视频助手套件中上传和处理音频文件。它允许用户上传音频文件，并指定音频处理的开始时间和持续时间。此节点对于需要音频操作或分析的应用至关重要，为套件中的进一步音频相关操作提供基础。
|
|
|
|
## Input types
|
|
### Required
|
|
- audio
|
|
- 指定要上传和处理的音频文件。此参数对于确定将进行处理的音频内容至关重要。
|
|
- Comfy dtype: COMBO[STRING]
|
|
- Python dtype: str
|
|
- start_time
|
|
- 定义应处理音频文件的起始点（以秒为单位）。此参数允许选择性地处理音频内容，增强灵活性。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- duration
|
|
- 指定应从开始时间处理音频的持续时间（以秒为单位）。这允许精确控制要分析或操作的音频文件片段。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
## Output types
|
|
- audio
|
|
- Comfy dtype: VHS_AUDIO
|
|
- 表示处理后的音频数据，准备在套件中的后续操作中使用。
|
|
- Python dtype: torch.Tensor
|
