Public Member Functions
	MultiplexingWaveProvider (IEnumerable< IWaveProvider > inputs)
	Creates a multiplexing wave provider, allowing re-patching of input channels to different output channels. Number of outputs is equal to total number of channels in inputs.
	MultiplexingWaveProvider (IEnumerable< IWaveProvider > inputs, int numberOfOutputChannels)
	Creates a multiplexing wave provider, allowing re-patching of input channels to different output channels.
int	Read (byte[] buffer, int offset, int count)
	Reads audio data from the input buffer and writes it to the output buffer.
void	ConnectInputToOutput (int inputChannel, int outputChannel)
	Connects the input channel to the output channel.

Properties
WaveFormat	WaveFormat [get]
	The WaveFormat of this WaveProvider.
int	InputChannelCount [get]
	The number of input channels. Note that this is not the same as the number of input wave providers. If you pass in one stereo and one mono input provider, the number of input channels is three.
int	OutputChannelCount [get]
	The number of output channels, as specified in the constructor.

Constructor & Destructor Documentation

MultiplexingWaveProvider() [1/2]

NAudio.Wave.MultiplexingWaveProvider.MultiplexingWaveProvider ( IEnumerable< IWaveProvider > inputs )

inline

Creates a multiplexing wave provider, allowing re-patching of input channels to different output channels. Number of outputs is equal to total number of channels in inputs.

Parameters

inputs

Input wave providers. Must all be of the same format, but can have any number of channels

MultiplexingWaveProvider() [2/2]

NAudio.Wave.MultiplexingWaveProvider.MultiplexingWaveProvider ( IEnumerable< IWaveProvider > inputs, int numberOfOutputChannels )

inline

Creates a multiplexing wave provider, allowing re-patching of input channels to different output channels.

Parameters

inputs	Input wave providers. Must all be of the same format, but can have any number of channels
numberOfOutputChannels	Desired number of output channels. (-1 means use total number of input channels)

Member Function Documentation

ConnectInputToOutput()

void NAudio.Wave.MultiplexingWaveProvider.ConnectInputToOutput ( int inputChannel, int outputChannel )

inline

Connects the input channel to the output channel.

Parameters

inputChannel	The input channel to be connected.
outputChannel	The output channel to be connected.

Exceptions

ArgumentException

Thrown when the input channel or output channel is invalid.

Read()

int NAudio.Wave.MultiplexingWaveProvider.Read ( byte[] buffer, int offset, int count )

inline

Reads audio data from the input buffer and writes it to the output buffer.

Parameters

buffer	The output buffer to write the audio data to.
offset	The offset in the output buffer to start writing the data.
count	The number of bytes to read from the input buffer and write to the output buffer.

Returns

The number of sample frames read and written to the output buffer.

This method reads audio data from all input sources, even if the data is not needed, to keep them in sync. It then processes the input data and writes it to the output buffer based on the specified offset and count. The method modifies the output buffer in place.

Implements NAudio.Wave.IWaveProvider.
