Overview

Source buffer holding 1 wire of data

Discussion

The Boolean 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.

Type Definition

typedef struct _ModuleBooleanSource
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32* value;                                 // Array of interleaved audio real data.
} ModuleBooleanSourceClass;

 M=boolean_source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE)
 Creates a source module that allows you to inject Boolean 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.
