Merges multiple single-channel (mono) audio sources into a single multi-channel audio output. This Node is often used in conjunction with the Channel Splitter Node to produce rich stereo experiences, e.g. by applying different effects to different channels.
This node has a configurable number of Audio inputs. See the Number of channels setting. The individual channels are interpreted based on the number of channels used, see Audio Channels. Inputs on this Node only support single-channel (mono) sources. If a source with more than 1 channel is connected (e.g. a stereo source), the extra channels will be ignored (without down-mixing).
