ADOBE AUDITION 119 User Guide With very high settings, you can achieve interesting special effects (as in the preset Another Dimension). Stereo Chorus Mode The Stereo Chorus Mode settings are only active when working with stereo files. They determine where the individual voices will be placed in the stereo field, as well as how the original stereo signal will be interpreted. Average Left & Right Adobe Audition can either average the original left and right channels or keep them separate in order to preserve any stereo image that may already exist. If you leave the box unchecked, the stereo image will be preserved when processing a stereo source file. (For example, spatial binaural cues such as those that exist in reverberated audio or live stereo recordings will be preserved.) Note that there is no need to check this box if the sample was originally monophonic, as it will have no result - except that if the box is checked, Adobe Audition will process the sample more slowly. Add Binaural Cues Check this option to add separate delays to the left and right outputs of each voice. This can make each voice appear to be coming from a different direction, but only when played through headphones. If the audio is meant to be played through speakers, this option should be turned off. In addition, when you add binaural cues, the volume of the right channel for a voice panned all the way to the left is still significant. If no cues are added, no output will be sent to the right channel. This is why greater separation can be heard when listening through speakers if binaural cues aren't used. Narrow Field/Wide Field Slider Use this control to specify the stereo field of the Chorus Effect. Stereo Field denotes where in space instruments or other sources are placed within the L/R image of a stereo waveform. A waveform that contains sound sources that are spread widely from left to right is said to have a wide stereo field, while those having images that are centered around the middle are said to have a narrow stereo field. In the case of Adobe Audition's stereo field Settings, the narrower the stereo field, the greater the chance that the chorused voices will be placed in the center of the L/R stereo image. At a setting of 50%, all the voices are spaced evenly about a half circle from left to right. For example, if a thickness of 5 is used, each voice will be panned such that voice #1 will be to your left, voice #2 will be left-of-center, voice #3 will appear in the center, voice #4 will be right-of-center, and voice #5 will be on your right. At settings higher than 50%, the voices start migrating to the outer edges: voices to the left go farther to the left, and those to the right go farther right. • If you use an odd number of voices, then there will always be one voice directly in the center. • With an even number of voices, and very high stereo field settings, all voices are pushed either hard left or hard right. Output The final output can be a mix between the original input (dry) signal and the chorused (wet) signal. Ordinarily, both settings should be less than 100%; otherwise the overlaying of several voices may cause clipping. Dry Out This setting determines how much of the unprocessed signal is mixed into the final output. If you set it to zero, Adobe Audition adds the original voice to the number of processed voices (which is determined by the Thickness setting).
