(8.D.2.5) Source
Overview
Source buffer holding 1 wire of data
Discussion
The source module has an internal buffer holding 1 output wire's worth of data. The module continuously copies the data from the internal value buffer to the output wire. Since this is a source module, you must specify the number of channels, blockSize, and sample rate of the output pin.
The module also supports real and complex data. For complex data data, set the .value field to complex data in MATLAB. On the target, complex data is stored in interleaved fashion: real, imag, real, etc.

MATLAB Usage
File Name: source_module.m
M=source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE, ISCOMPLEX)
Creates a source module that allows you to inject test data into
the audio processing layout.
Arguments:
NAME - name of the module.
NUMCHANNELS - number of interleaved channels in each output pin.
By default, NUMCHANNELS=1;
BLOCKSIZE - number of samples per output channel. By default,
BLOCKSIZE=32.
SAMPLERATE - sample rate of the output signal in Hz. By default,
SAMPLERATE=48000.
ISCOMPLEX - Boolean indicating whether the output holds complex data.
By default, ISCOMPLEX=0.
