Overview

Uniformly distributed white noise generator

Discussion

Generates uniformly distributed random values at the sample rate in the specified range. Internally, the module uses a random number generator and then scales the values into the proper range.

Type Definition

Code Block
typedef struct _ModuleWhiteNoise
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    FLOAT32 range;                                // Generated noise will be in the interval [-range +range].
    awe_modRandInstance *rand; // Random number generator using a LCG algorithm
    awe_modTypeConversionInstance *int2flt; // Converts between numeric data types
    awe_modScalerV2Instance *scale; // General purpose scaler with a single gain
} ModuleWhiteNoiseClass;
