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
typedef struct _ModuleWhiteNoiseFract32
{
ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure
fract32 range; // Generated noise will be in the interval [-range +range]
awe_modRandInstance *rand; // Random number generator using a LCG algorithm
awe_modScalerFract32Instance *scale; // Linear multichannel scaler
} ModuleWhiteNoiseFract32Class;

M=white_noise_fract32_module(NAME, SR, NUMCHANNELS, BLOCKSIZE)
Creates a Fractional white noise generator for use in the Audio Weaver. The
module has a single multichannel output pin.
NAME - name of the module.
SR - sample rate of the output
NUMCHANNELS - number of interleaved channels in each output pin.
BLOCKSIZE - number of samples per output channel.
