Overview

Source buffer holding 1 wire of constant data

Discussion

The DC source int module has an internal variable holding one data value. The module continuously fills the output wire with the internal data value. Since this is a source module, you must specify the number of channels, block size, and sample rate of the output pin

Type Definition

typedef struct _ModuleDCSourceInt
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 value;                                  // Data Value
} ModuleDCSourceIntClass;

 M=dc_source_int_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE)
 Creates a source module that allows you to inject DC test data into
 the audio processing layout.  Arguments:
    NAME - name of the module.
    NUMCHANNELS - number of interleaved channels in each output pin.
    BLOCKSIZE - number of samples per output channel.
    SAMPLERATE - sample rate of the output signal, in Hz.
