ChannelMergerNode
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The ChannelMergerNode interface, often used in conjunction with its opposite, ChannelSplitterNode, reunites different mono inputs into a single output. Each input is used to fill a channel of the output. This is useful for accessing each channel separately, e.g., for performing channel mixing where gain must be separately controlled on each channel.
If ChannelMergerNode has one single output, but as many inputs as there are channels to merge; the number of inputs is defined as a parameter of its constructor and the call to AudioContext.createChannelMerger(). In the case that no value is given, it will default to 6.
Using a ChannelMergerNode, it is possible to create outputs with more channels than the rendering hardware is able to process. In that case, when the signal is sent to the AudioContext.listener object, supernumerary channels will be ignored.
| Number of inputs | variable; defaults to 6. |
|---|---|
| Number of outputs | 1 |
| Channel count mode | "explicit" |
| Channel count | 2 (not used in the default count mode) |
| Channel interpretation | "speakers" |
