Analyzing Phase, Frequency, And Amplitude - Adobe AUDITION 3 User Manual

Adds a constant DC (Direct Current) amplitude to the tone, centering the waveform by shifting it up or
DC Offset
down by the specified percentage. For example, you can apply DC Offset to correct an incoming signal that has
suffered electrical pollution from a strong adjacent current.
Specifies the type of waveform to use. Each flavor has a particular sound unique unto itself. Sine waveforms
Flavor
are fundamental, with no harmonics (pure tone). Triangle waveforms have odd harmonics with amplitude of 1 to
itself (squared). Square waveforms have odd harmonics with amplitude of 1 to itself. Sawtooth waveforms have all
harmonics with amplitude of 1 to itself.
Specifies the length of the generated tone (in seconds). Use decimals for partial seconds. For example,
Duration
enter .25 to generate tones for exactly one-fourth of a second.
When a range of audio data is selected, causes the audio to be ring modulated, or multiplied, by the current
Modulate
tone settings. This option is great for adding special effects.
When a range of audio data is selected, causes the audio to be demodulated. Use Demodulate on a
Demodulate
previously modulated source to produce interesting effects.
When a range of audio data is selected, mixes the generated tones on top of the selected audio.

Analyzing phase, frequency, and amplitude

Techniques for analyzing audio
Edit View provides several ways to analyze audio. To compare phase relationships between the left and right stereo
channels, use the Phase Analysis panel. To analyze tonal and dynamic range, use the Frequency Analysis panel and
the Amplitude Statistics dialog box.
Edit View also provides Spectral Frequency, Spectral Pan, and Spectral Phase displays, which you can use in
conjunction with the analysis methods above. (See "Displaying audio in Edit View" on page 65.)
Analyze phase
In Edit View, you can use the Phase Analysis panel to reveal out-of-phase channels for stereo waveforms, which you
can correct with the Invert command. Phase analysis also shows stereo separation, which you can adjust using stereo
imagery effects. (See "Changing stereo imagery" on page 162.)
To evaluate phase in detail, use the Phase Analysis panel in conjunction with Spectral Phase Display. (See "About
Spectral Phase Display" on page 67.)
