# Documentation
|
|
- Class name: SaltAudioSimpleReverb
|
|
- Category: SALT/Audio/Effect
|
|
- Output node: False
|
|
|
|
SaltAudioSimpleReverb节点为音频输入添加混响效果，模拟物理空间的声音反射特性。它允许调整混响水平和衰减以定制效果。
|
|
|
|
# Input types
|
|
## Required
|
|
- audio
|
|
- 将应用混响效果的音频输入。它作为混响模拟的原始素材。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
|
- reverb_level
|
|
- 确定应用于音频的混响效果强度，影响虚拟空间的感知大小和反射性。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- decay
|
|
- 控制混响效果的衰减速率，模拟模拟空间的吸收特性。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
# Output types
|
|
- audio
|
|
- 应用了混响效果的音频输出，模拟具有混响特性的空间的声学特征。
|
|
- Comfy dtype: AUDIO
|
|
- Python dtype: bytes
|
