194 CHAPTER 9 Generate Menu - Edit View DC Offset The DC Offset value entered here adds a constant DC ("Direct Current") amplitude to the tone, which shifts the entire waveform up or down by the specified percentage. Flavor Use this drop-down list to choose the type of waveform to use. Each flavor has a particular sound unique unto itself. • SineFundamental, no harmonics (pure tone) • TriangleOdd harmonics with amplitude of 1 to itself (squared) • Square Odd harmonics with amplitude of 1 to itself • SawtoothAll harmonics with amplitude of 1 to itself Duration This setting lets you enter the length of the generated tone (in seconds). Feel free to use decimals for partial seconds. For instance, entering .25 in the Duration field will generate tones for exactly one-fourth of a second. Source Modulation Choose an option for modulation: • Modulate: With this option checked, instead of generating new tones, the currently highlighted wave data is be "ring modulated", or multiplied, by the current tone settings. This is great for adding really weird special effects. Note: If you check the Modulate option, make sure that a section of the active waveform is highlighted. • Demodulate: Like Modulate, Demodulate requires a highlighted selection. Demodulate can be used on a previously modulated source with interesting effects. • Overlap (mix): Checking this option will mix the generated tones on top of the selected audio. Presets This section allows you to recall and manage Generate Tones presets. More information about Presets can be found in the "Looking at the Work Area" chapter. Preview Press this button to audition the current Generate Tones settings before you apply them to the active waveform.
