The Noise Generator
This noise generator produces white and pink noise, and has independent burst/ pause ratio, total time, and repetitions. White and pink noise are random signals that include all of the audio frequencies. The noise simulates the random thermal motion of electrons. When either white or pink noise is amplified, we perceive the sound as hiss. White noise has a flat linear frequency response, while pink noise has a flat logarithmic frequency response (as shown by a logarithmic Spectrum Analyzer).
Level
Use your mouse to select an output level ranging from off to 0 dB RMS of a
Noise Duration: Burst/Pause Ratio
This ratio refers to the percentage of burst vs. pause that is applied to the generated noise. This pause interval can be assigned to any increment between 0 seconds (off) and 100 seconds (full). To adjust the ratio, use your mouse to select the up/down arrows, or scroll the numbers in the small window, or grab the blue bar graphic and move it left or right.
Noise Duration: Total Time
This refers to the combined length of the burst and the pause. This increment can be assigned to any interval between 0 seconds (off) and 60 seconds. Use the mouse to select the up or down arrows or to scroll the digit.
Repetitions
Repetitions refer to the number of repetitions of the noise bursts. The number of repetitions can be selected to repeat a sequence over any number of times between 1 and infinity.
Noise Type: White
White noise is unfiltered, unaltered thermal noise just like you hear when you turn your amplifier all the way up to listen to the noise floor.
Noise Type: Pink
Pink noise is white noise that has been filtered with a pinking filter. This is a 3 dB per octave
