(8.D.2.3) SourceInt

Overview

Source buffer holding 1 wire of integer 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

Type Definition

typedef struct _ModuleSourceInt { ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure INT32* value; // Array of interleaved audio data } ModuleSourceIntClass;

MATLAB Usage

File Name: source_int_module.m

M=source_int_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE, ISCOMPLEX) Creates a source module that allows you to inject integer 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 source module holds complex data. By default ISCOMPEX = 0 (real).
