(8.D.1.2) BooleanSource

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;

MATLAB Usage

File Name: boolean_source_module.m

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.
