Markers
There are four markers within CEDAR Cambridge that you can insert simply by clicking on the appropriate icon. These then appear in the same position in all CEDAR Cambridge modules that use them, allowing instant transfer of frequency information between modules. Once inserted, these markers may be moved freely as needed.
In addition, many processing modules have 'Set To Marker' controls that snap the appropriate parameter to any one of the Markers that you have defined elsewhere in CEDAR Cambridge. So, for example, you can identify the fundamental frequency of a hum using a Marker in the high resolution Spectrum Analyser, and then use this Marker in the Debuzz or EQ modules to eliminate the problem.
