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.
TheChannelMergerNode 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.
IfChannelMergerNode 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 toAudioContext.createChannelMerger(). In the case that no value is given, it will default to6.
Using aChannelMergerNode, 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 theAudioContext.listener object, supernumerary channels will be ignored.
| Number of inputs | variable; defaults to6. |
|---|---|
| Number of outputs | 1 |
| Channel count mode | "explicit" |
| Channel count | 2 (not used in the default count mode) |
| Channel interpretation | "speakers" |
