====== User Interface ======

{{:wiki:bedienung:pgof_oben.png?nolink&}}

  - Open file into Active Curve
  - Save Active Curve to file
  - Choose or disable Active Workspace (determines default directory for program operations; necessary for proper operation of Room Macros)
  - Clear all loaded Curves
  - Clear the Active Curve
  - Go Back one step
  - Make Active Curve thicker
  - If WriteConf is checked demand confirmation when saving a curve which will overwrite an existing file
  - Displays the current Active Workspace directory path
  - Enables selection of the Active Curve for any process steps until another Active Curve is selected. Needed before file open, save, or edit. If a curve number is underlined here, it contains unsaved data
  - Sample rate assumed by Acourate for all currently open curves. Must be set BEFORE opening a file. Should not be changed without clearing all curves before further processing
  - Charts to View: Amplitude (vs frequency); Phase (vs frequency, including unwrapped phase and group delay); value (usually pressure) (vs Time); Amplitude vs frequency and value vs Time; All three available charts

Data for the current cursor position:

  - Sound level and frequency
  - Time for one full cycle at this frequency
  - Wavelength based on speed of sound in dry air at 21.35 degrees Celcius
  - 1/4 Wavelength - see [[:en:wiki:anhang:glossar:allison-effekt|Allison Effect]] in Glossary

  - Filename and illustrated color of the loaded curves (remove checkmark and curve is no longer displayed)
  - Number of frequency points of the curve
  - Maximum level of the entire curve in dB which occurs at stated frequency
  - Minimum level of the entire curve in dB which occurs at stated frequency
  - Maximum level within the marked area
  - Minimum level within the marked area
  - Difference between the two levels
  - Level at frequency on the left mark
  - Levelat frequency on the right mark
  - Difference between the two levels

Returns the data from the current cursor position in the time domain.

  - X-axis - Time in seconds at cursor position
  - Y-axis - value of time signal at cursor position
  - Sample - Time in whole samples at cursor position

  - Number of total samples of a time signal
  - Maximum value for samples
  - Minimum value in samples
  - Maximum value within the marked area
  - Minimum value within the marked area
  - Total time of the sound signal in the selected interval
  - Distance traveled by sound during the selected interval
  - Number of samples in the selected interval
  - Frequency whose whole cycle time equals the selected interval (1 / cycle time)
