The Noise command lets you generate random noise in a variety of colors. (Traditionally, color is used to describethe spectral composition of noise. Each color has its own characteristics.) Generating noise is useful for creating soothing sounds like waterfalls (perfect for use with the Binaural Auto-Panner function of Adobe Audition) and for generating signals that can be used to check out the frequency response of a speaker, microphone, or other audiosystem component.
Color
Specifies a color for the noise:
Style
Specifies a style for the noise:
Intensity
Specifies the intensity of the noise on a scale of 2 to 40. At higher intensities, the noise becomes more erratic and sounds harsher and louder.
DC Offset
Adds a constant DC (Direct Current) amplitude to the tone, centering the waveform by shifting it up or down by the specified percentage.
Duration
Determines the number of seconds of noise that Adobe Audition generates.
Choose Effects > Generate > Tones to create a simple waveform using several amplitude‑ and frequency‑related settings. Generated tones are great starting points for sound effects.
Sweep Frequencies
Transitions tones from settings on Start tab to those on End tab. (Waveform remains constant.)
Base frequency
Specifies the main frequency to be used for generating tones.
Modulation Depth
Modulates pitch of the base frequency over a user‑defined range. For example, a 100 Hz setting modulates the original frequency from 50 Hz below to 50 Hz above.
Modulation Rate
Specifies how many times per second the frequency modulates, producing a warbling, vibrato effect.
Waveform
Choose one of the following:
Frequency Components
Adds up to five overtones to the fundamental frequency (Base Frequency). Below the sliders, enter either a specific frequency for each overtone, or specify a multiplier of the fundamental. Then, use the Amplitude sliders to mix overtones in proportion to one another.
Volume
Specifies the overall output of the effect.
Duration
Specifies the length of the generated tone in the format currently specified for the time ruler. Right-click the numbers to choose a separate time format for Generate Tones.
To access the following options, click Advanced:
Start Phase At
Specifies the starting location in the waveform cycle. If set to 0°, waves will start at the zero-crossing point. If set to 90°, the wave will start at full amplitude (generating a noticeable click).
2nd Channel Phase Difference
Adjusts the relative phase of stereo channels. A value of zero places the channels completely in phase and 180 places them completely out of phase.
Change Speed
Dynamically changes the relative phase between the two channels of a stereo audio file over time. For example, if you enter 1 Hz, the phase difference will cycle through 360° each second.
DC Offset
Adds a Direct Current offset, shifting the center of the waveform up or down by the specified percentage. Use this adjustment to calibrate audio hardware or simulate hardware-induced offset.
With Selected Audio
Choose from the following:
Adobe Audition is a powerful application for recording and mixing audio, podcasting, and sound effect design.
