Crossfade
Blend two signals with one balance control: 0 plays A, 1 plays B.
- Utility
- Since 0.1.0
- blend
- crossfade
- balance
- mix
Crossfade blends two audio signals with a single balance control.
What it does#
The node has two inputs, A and B, and one output. Balance 0 passes input A, balance 1 passes input B, and values between blend them. It is useful for dry/wet-style blends and for switching between two sources smoothly. An input that is not connected is silent.
When to use it#
Use it to pick between two sources or two processing chains with one knob. To add several signals together at independent levels, use Mixer.
Ports#
| Port | Direction | Signal | Lanes |
|---|---|---|---|
a | Input | Audio | Inferred from the cable |
b | Input | Audio | Inferred from the cable |
audio | Output | Audio | Inferred from the cable |
Parameters#
| Parameter | Label | Range | Default | Unit | Scale | Notes |
|---|---|---|---|---|---|---|
balance | Balance | 0 to 1 | 0.5 | linear | Blend between inputs A and B. 0 selects A; 1 selects B. |
Balance (balance)#
Blend between input A and input B, from 0 to 1. 0 selects A and 1 selects B. The center position blends both.
Tips#
- Feed the same source into A and a processed copy into B to build your own dry/wet control.
- Both inputs must have matching channel counts unless an adaptation policy is set. See Multichannel audio.
