Analyzer Reference

To visualize the frequency spectrum in the processing chain at input or output of a frequency-domain PlugIn loaded into the PlugIn Station, select the corresponding signal source from the drop-down list belonging to the red or green display channel respectively.

Note that the Analyzer window will remain black as long as no signal is played back.

The white display channel may be set to the filter characteristic of the High-Low Cut PlugIn, or to the noise profile currently used in the DeNoiser PlugIn. These curves can be displayed simultaneously with any two spectrum lines pre-chosen from the drop down lists.

When loading the DeNoiser PlugIn prior to the Analyzer PlugIn, the Analyzer will be automatically set up to display the input (red) and output (green) spectrum of the DeNoiser PlugIn as well as the currently selected noise profile (white).

To zoom in or out of the currently displayed frequency range, click on the arrow buttons below the frequency scale. The same applies for the amplitude range; zooming in or out is achieved by clicking on the arrows to the right of the dB scale.

To switch between the logarithmic and linear amplitude scale, click the appropriate checkbox at the upper right corner of the window (log).

The decay parameter controls the fallback time of the display. Its optimal value has to be in accordance with the usage of the Analyzer PlugIn. For higher decay times, the frequency spectrum display behaves more inertly or smoothly; for the lower values the time resolution is better, but the display becomes too restless. In general, the higher values are convenient for average spectrum measurements, while the lower if short transients have to follow. So, depending on your purpose, use the display and choose a convenient value for the decay parameter.
