- Class name: SaltAudioStereoMerge
|
|
- Category: SALT/Audio/Effect
|
|
- Output node: False
|
|
|
|
SaltAudioStereoMerge节点旨在将两个单声道音频输入合并为一个立体声音频输出。它确保两个音频输入的长度相同，并在合并为立体声轨道之前将它们转换为单声道（如果它们尚未转换）。
|
|
|
|
# Input types
|
|
## Required
|
|
- audio_a
|
|
- 要合并的第一个音频输入。它被视为结果立体声音频中的一个声道。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
- audio_b
|
|
- 要与第一个输入一起合并的第二个音频输入。它与第一个输入相辅相成，形成立体声音频输出。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
|
|
# Output types
|
|
- audio
|
|
- 通过合并两个输入音轨而产生的立体声音频输出。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
