STK noise generator.
Generic random number generation using the C rand() function. The quality of the rand() function varies from one OS to another.
by Perry R. Cook and Gary P. Scavone, 1995–2023.
stk::Noise::Noise | ( | unsigned int | seed = 0 | ) |
Default constructor that can also take a specific seed value.
If the seed value is zero (the default value), the random number generator is seeded with the system time.
void stk::Noise::setSeed | ( | unsigned int | seed = 0 | ) |
Seed the random number generator with a specific seed value.
If no seed is provided or the seed value is zero, the random number generator is seeded with the current system time.
Fill a channel of the StkFrames object with computed outputs.
The channel
argument must be less than the number of channels in the StkFrames argument (the first channel is specified by 0). However, range checking is only performed if STK_DEBUG is defined during compilation, in which case an out-of-range value will trigger an StkError exception.
Implements stk::Generator.
