Splits a multi-channel audio or control signal (such as a stereo signal) to individual single channel signals. This is useful if you only want to apply an effect to one channel in a signal (e.g. to add a gain change or pitch change to the left channel only).
Use the Channel Merger Node to reconstruct the multi-channel signal from its individual channel components.
Inputs
Audio Input
An audio or control signal to split.
The channel count of this input should match the Number of channels setting for correct behavior. If they don’t match, the Channel Splitter Node will automatically upmix or downmix the signal first, to match the Number of channels setting, before splitting it further into its various outputs.
Num Channels-Control Input
A constant input to control the Number of channels setting. This input only accepts a constant value. Values are automatically rounded to the nearest integer.
Settings
Number of Outputs
The number of outputs created on the Channel Splitter Node, and consequently, the maximum Number of channels supported.
Number of Channels
The number of actual channels to process. By default, this matches the Number of outputs setting, but you can override it. If you override it, you can also control this setting through the Num channels-control input. When overriding, and the value is lower than the Number of outputs setting, the extra outputs are simply unused.
Outputs
Audio Output 1-32
This Node has a variable number of outputs. This is what the Number of outputs setting determines. The channel layout depends on the number of channels used, see Channel Matching & Mixing.
Each output is a single-channel (mono) signal. These outputs support constant folding in 2 cases:
- If the input is constant, all outputs are constant too
- If you override the Number of channels setting, outputs ignored as a result will be a constant 0
Limitations & Known Issues
The Channel Merger Node does not accurately visualize individual outputs as distinct audio or control signals (blue and orange, respectively). Instead, if the input signal is determined to be an audio signal (blue), all outputs will be considered audio signals as well. Same for control signals.
This visualization limitation has no effect on the actual signal contents.
