Profile Settings Dialog (Waveform and Segmentation Viewer)
This is the setup and start dialog for the Waveform & Segmentation Viewer application. You reach this dialog by selecting a Waveform & Segmentation Viewer profile in the Workspace and selecting 'Settings' from the context menu.
At the top of the dialog window the control buttons and the controls for the source signal selection are located. Below the source signal controls the controls for the application settings are displayed in two groups. On the left side are the settings for the three plot regions zoom, segment lines and overview and on the right side are the general settings and some buttons for sub-dialogs.
- Save settings into the profile displayed in the dialog caption, close the dialog and start the application. This button is only displayed if one or more signals are selected in the Overview or Detail window of the Workspace. If multiple signals are selected, for each signal a separate application is started.
- Save settings into the profile displayed in the dialog caption and close the dialog, but do not start the application.
- Close the dialog without saving the changes. Note: The Start button is only displayed if a valid object is selected in the Workspace (e.g. a segment or sound file).
- Shows the XML-reference (IRef) of the audio-set containing the source signal
- Contains the ID of the selected segment or the address (task-expression) of the source signal. This field can be edited.
- Source signal channel (All, 1, 2, ...). The contents of the combobox depend on the number of channels of the audio-set. Note: If multiple source signals are selected, only the number of selected signals (on the left side) and the Chn.-selection is displayed, the Set- and Seg-controls are hidden.
- Show (check) or hide (not checked) the zoom window(s).
- Set the relative height of zoom region. Note that this can also be set in the General Settings dialog.
- Range of amplitude-scale of the zoom window(s). If the in % box is checked the range is specified in percent of the full range value (see General Settings), otherwise range is an absolute signal amplitude value. The value of this field must be greater than zero. The amplitude-scale of the zoom window is scaled from –range to +range.
- If checked, only the envelope of the waveform is displayed, otherwise the waveform function is filled.
- Length of the signal displayed in the zoom window in milliseconds. This value is used for zoom-windows displaying the mode around-active. In this case the time-scale of the zoom-window is scaled from –window/2 to +window/2.
- Selects the cursor style
- function bound
- If checked, the Y-position (amplitude) of the cursors are bound to the waveform function, otherwise the cursor can be moved free.
- rubber line
- If checked, a rubber line is drawn between the two cursors
- Selects the function line style and color for the zoom window waveform function (see Color Schemes)
- This field selects one of three available zoom modes: between-cursors (one zoom window containing the signal between the two segment lines cursors), around-active (one zoom window containing the signal around the active/selected segment lines cursor) or around-both (two zoom windows each containing the signal around one cursor of the segment lines region).
Segment Lines Settings
- Number of display lines for waveform of source segment. This number must be in the range 1 to 8.
- height, envelope, range, in %, cursor, line
- See zoom settings.
- show segments
- If checked, the segment markers for all segments in the range of the signal plotted in the segment lines graphs are shown. The marker format and style and the displayed text are configured in the segment markers dialog which can be opened with the button Segs.
- Open the segment marker settings dialog.
- timebar only
- If checked, only the time scale is displayed but the signal waveform is not plotted. This can be useful if the sound file is very long, since plotting a long file takes time.
For the other settings read the description of the settings for segment lines and zoom.
- Automatic Printout
- If checked, the printout of the waveform plot is started automatically and the application is closed when the printout is finished. The button starts the print settings dialog.
- do not print cursor
- If checked, the cursors are not printed. This option only works for the automatic printout.
- Automatic Segment Names
- If checked, the id of new segments is assigned automatically. The format of the automatic name depends on the settings of the Automatic Segment Names dialog, which can be opened with this button.
- show x grid, show y grid
- Enable/disable the grid on the x/y-scales of the waveform plot.
- show dialog
- If checked, the control and segmentation dialog of the waveform plot application is shown, otherwise in is hidden.
- enable one-click range selection
- If checked, you can set a new cursor range by clicking anywhere in the graph, dragging and letting go. This can make selecting a cursor range very easy. However, if you prefer to be able to change the cursor range only by selecting a cursor and dragging it, please disable this check box.
- Color Scheme
- With this button the Color Scheme and Settings dialog is opened to select and/or configure the plot colors, line styles and general graphics settings. The selected color scheme is displayed in the button caption.
- signal attenuation
- The amplitude value of the full signal attenuation. This value must be greater than zero.
- draw frames
- Number of frames (blocks) to be used for plotting long signals. This number is set to 100 by default and must be greater than 2. It can be used to optimize the graphics transfer rate. Normally it need not to be changed.
- play window
- Set length (in milliseconds, greater than 0) and position (before/after selected cursor) of the play window. The waveform plot application plays the signal of the play window, when the space-bar is pressed.
- Select which unit should be used for the time axis (x axis). If 'layout defaults' is specified, the settings defined in the Display Layout and Format dialog are used.
- amplitude scale
- If set to 'automatic', the optimal amplitude scale based on the selected signal is used, otherwise the graph's 'range' settings are used.
