.H 1 "DSP processing nodes"

DSP processing nodes perform DSP operations on the data in their input
channels
and write the results to their output channels. There can be any number
of input or output channels. For example there are nodes that do multiplexing
(combine multiple channels into a single channel) and demultiplexing
(the inverse). The number of input channels is displayed as an integer
on the left of each node in a network. (If no integer is displayed there
is a single input channel.) Similarly the number of output channels is
displayed on the right. Each output channel of a node can have multiple
buffers. The number of buffers is displayed in a small box to the right
of the node. Each buffer is a copy of the same data stream. In contrast
the different channels in a node ordinarily contain different data. For
example in a node for demultiplexing each output channel will represent
one of the demultiplexed data streams.

To access the DSP processing nodes select `objects'
and `dsp processing'.
