322 CHAPTER 18 Effects Menu - Multitrack View Presets The Frequency Splitter effect supports Presets for storing and recalling your favorite settings. More information about Presets can be found in the "Looking at the Work Area" chapter. Vocoder A vocoder is a special effect which takes two inputs, usually an instrument of some kind and a voice, and modulates one signal (the process signal, usually the instrument) with the input of the other (the control signal, usually the voice). Specifically, the amplitude of given frequencies in the process signal are made to fluctuate in response to the same amplitude changes in the control signal, allowing for the sound of one instrument to be "controlled" with the other. In the example above, the instrument (the process sound) could be made to "sing" by affecting it with the voice (the control sound). Vocoder Dialog To initiate Adobe Audition's Vocoder effect: • Position the wave blocks so that the sections you want to process together are lined up. • Make a selection that covers the part of both wave blocks you want to process. • Ctrl+Left-click each wave block you wish to process to give them focus. • Access the Vocoder from the Effects pull-down menu, the Effects toolbar, or the Effects section of the Organizer window. The following are the major components of the Vocoder window: Control Wave From this drop-down list, choose the waveform (from any that are already active in the session) to act as the control signal. This is usually a vocal of some kind. Process Wave Use this drop-down list to select the waveform (from any currently open in the session window) to act as the process signal. This is normally some kind of synthesized sound to use to replace the vocal chords. Output To Choose the track to output the resulting waveform. This entry defaults to the next available track. FFT Size The FFT Size parameter specifies the size of the FFT to use, which can affect processing speed and quality.
