syz_createNoiseGenerator

SYZ_CAPI syz_ErrorCode syz_createNoiseGenerator(syz_Handle *out, syz_Handle context, unsigned int channels,
                                                void *config, void *userdata,
                                                syz_UserdataFreeCallback *userdata_free_callback);

Creates a NoiseGenerator configured for uniform noise with the specified number of output channels. The number of output channels cannot be configured at runtime. Each channel produces decorrelated noise.

Properties

Linger Behavior

Fades out over a few milliseconds.

Remarks

NoiseGenerators generate noise. This is most useful when filtered via the source, and can make things such as plausible if low-quality wind and whistling effects.

Synthizer allows setting the algorithm used to generate noise to one of the following options. Note that these are more precisely named than white/pink/brown; the sections below document the equivalent in the more standard nomenclature.

SYZ_NOISE_TYPE_UNIFORM

A uniform noise source. From an audio perspective this is white noise, but is sampled from a uniform rather than Gaussian distribution for efficiency.

SYZ_NOISE_TYPE_VM

This is pink noise generated with the Voss-McCartney algorithm, which consists of a number of summed uniform random number generators which are run at different rates. Synthizer adds an additional random number generator at the top of the hierarchy in order to improve the color of the noise in the high frequencies.

SYZ_NOISE_TYPE_FILTERED_BROWN

This is brown noise generated with a -6DB filter.
