Use graphical representations

Graphical representation can be used in temporal view and in timeline. In temporal view, you can add several representations and manage them through layers. In timeline, you only can add one representation apart from waveform and sonogram.

To add a representation in temporal or timeline view:

  1. Open property panel.
  2. Select the second tab.
  3. Click on + button.
  4. Select a type of representation. This menu only shows representations that are compatible with imported files.
  5. Select the new representation to display its properties.

Main properties

In timeline, you only can change opacity of representation. In temporal view, you have more settings:

  1. Opacity.
  2. Background color (default = transparent).
  3. Vertical position and height.
  4. Use advanced button to change previous settings for all representations: Automatic vertical distribution.
  5. Visibility of vertical ruler.

Not all representations have vertical ruler. You also can show information to read values of representation.

Waveform

  1. Use File to select an audio or video file.
  2. Channel: Display all channels or only the result of a mix. You can also specify visible channel (see Advanced file menu at the bottom of this page).
  3. Color: Change default color.
  4. Or Use color of series. These colors are specified in the advanced menu (see Advanced file menu at the bottom of this page).

Sonogram

  1. Use File to select an audio or video file (see also Advanced file menu at the bottom of this page).
  2. Dynamics: Change intensity of colors.
  3. Advanced colors: See Advanced colors at the bottom of this page.
  4. High and Low: Visual top and bottom position.
  5. Parameters: Settings used for computation.

Data: Graph visualization

See Import data files for more details on the structure of data files.

  1. Use File to select a data file (see also Advanced file menu at the bottom of this page).
  2. Select a line or a plain graph with Type.
  3. Width: Width of line.
  4. layer: When data has several series, draw all of them layered.
  5. Color of graph.
  6. Or Use color of series. These colors are specified in the advanced menu (see Advanced file menu at the bottom of this page).

Data: Gradient visualization

See Import data files for more details on the structure of data files.

  1. Use File to select a data file (see also Advanced file menu at the bottom of this page).
  2. Intensity: Change intensity of colors.
  3. Advanced colors: See Advanced colors at the bottom of this page.
  4. Sample: Number of used colors.

Data: Complex visualization

See Import data files for more details on the structure of data files.

Complex representation only uses the first serie of each data.

  1. Use Y file to select a data file for Y value (see also Advanced file menu at the bottom of this page).
  2. Use Width file to select a data file for the width of line.
  3. [Optional] Use Color file to select a data file for the color.
  4. Margin: Add a top and bottom margin.
  5. Color #1 and Color #12: Use with Color file parameter. The flow graph is drawn between these 2 colors.
  6. Draw Y value and Color is used to draw the exact value of Y.

Data: Frequency visualization

You can use this representation to visualize fundamental frequency estimation computed with the audio descriptor or imported from the Tony software.

See Compute descriptors to learn how to calculate audio descriptors.

See Import Tony Pitch Track Data files for more details on importing from Tony.

Frequency visualisation only uses the first serie of each data.

  1. File: Select the data file.
  2. Width and Color: Select size and color of the drawing.
  3. Filters > Reduce pitch range: Change range of the drawing with Min and Max parameters.
  4. Filters > Filter from amplitude: Use an audio File to remove values under an amplitude value (Threshold).
  5. Filters > Maximum pitch interval: Remove values from interval above the semitone parameter.
  6. Filters > Delete octave jumps: Octave corrections.
  7. Use Horizontal guides to add horizontal lines that correspond to pitches.
  8. Use Color to change global color of lines. Each line can also have a custom color (see below).
  9. Use Fine tune to move all lines +/- 100 cents (see below for cents definition).
  10. Use the first + to add a line.
  11. Use the second + to add several lines computed from the most frequent frequencies.
  12. Use the second - to delete selected line in the table.

Each line of the table contains:

  1. The name of the line that will be displayed in the floating vertical ruler (See Main properties above).
  2. A decimal value representing MIDI + cents. For example 63.72 = 63 (MIDI) and 72 cents.
  3. The size of the interval with the previous line in cents (100 cents = a semitone). This value is only computed and cannot be edited.
  4. A custom color.

Multidimentional visualization

  1. Use File to select an audio or video file (see also Advanced file menu at the bottom of this page).
  2. Intensity: Change intensity of colors.
  3. Advanced colors: See Advanced colors at the bottom of this page.

Piano roll

  1. Use file to select a score file (see also Advanced file menu at the bottom of this page).
  2. If you select a MusicXML file, you can Show source.
  3. Color of score.
  4. Or Use color of part. These colors are specified in the advanced menu (see Advanced file menu at the bottom of this page).
  5. Reduced range shows a focused score from low to high note.
  6. Change how the Velocity is displayed.
  7. Add horizontal line for C positions.
  8. Show/Hide Measures and select a Color.

Session

  1. Use file to select a session file (see also Advanced file menu at the bottom of this page).
  2. Color of all clips.
  3. Or Use color of tracks. These colors are specified in the advanced menu (see Advanced file menu at the bottom of this page).
  4. Show/Hide Titles of clips.
  5. Show/Hide Markers and select a Color.

Advanced file menu

Depending on the representation, you can access one or both of the following advanced functions.

Select Series

This window lists the series of the data file. You can show/hide series and change their display colors.

Transform Data

This window allows you to apply effects to the data.

Advanced colors

This window allows you to change the colors of sonogram and multidimentional representations:

  1. Select a preset
  2. Select a type of colors.
  3. Change color parameters.

To save setting:

  1. Enter a title.
  2. Click on +.

To delete a preset:

  1. Select a preset you have created (you cannot delete predefined presets at the top of the list).
  2. Click on -.
