noise.colored~

colored noise generator with an arbitrary spectral roll

available since version: 0.9.6

---

information

Generates a colored noise signal with an arbitrary spectral roll-off factor (alpha) over the entire audible frequency range (20-20000 Hz). The output is normalized so that an equal RMS level is maintained for different values of alpha.

arguments:

• ALPHA slope of roll-off, between -1 and 1. -1 corresponds to brown/red noise, -1/2 pink noise, 0 white noise, 1/2 blue noise, and 1 violet/azure noise.
  type: float
  

methods:

• blue set to blue noise (roll-off factor 0.5)
  

• brown set to brown/red noise (roll-off factor -1)
  

• pink set to pink noise (roll-off factor -0.5)
  

• velvet set to velvet noise (roll-off factor 1)
  

• white set to white noise (roll-off factor 0)
  

properties:

• @alpha Get/set slope of roll-off, between -1 and 1. -1 corresponds to brown/red noise, -1/2 pink noise, 0 white noise, 1/2 blue noise, and 1 violet/azure noise.
  type: float
  range: -1..1
  default: 0
  

• @active Get/set on/off dsp processing
  type: bool
  default: 1
  

• @osc (initonly) Get/set OSC server name to listen
  type: symbol
  

• @id (initonly) Get/set OSC address id. If specified, bind all properties to /ID/noise_colored/PROP_NAME osc address, if empty bind to /noise_colored/PROP_NAME.
  type: symbol
