13. Visualisation

Soundprobe offers a number of ways to visualise the sound input and output from within Soundprobe. You may open as many of these as your system has resource for, each may have its own settings, screen position and each can monitor the sound input or output independently.

To open a new visualisation:

1. Select the Visualisation menu.
2. Select the type of visualisation you want to open from the menu list.

To close all visualisation:

• Select Visualisation > Close All.

To reload all visualisation at startup:

1. Select Tools > Properties.
2. Select the Options tab to display the options pages.
3. Enable the Load Last Visualisation At Startup option.
4. Click OK or Apply to set the changes.

To open the properties for a visualisation:

1. Right-click within the visualisation to display the visualisation pop-up menu.
2. Select Properties.

To select sound input or output monitoring:

1. Right-click within the visualisation to display the visualisation pop-up menu.
2. Select Input or Output.

To close a visualisation:

• Click the close icon on the visualisation window.

To disable or enable a visualisation:

1. Right-click within the visualisation to display the visualisation pop-up menu.
2. Deselect or select the Enable option from the pop-up menu.

To resize a visualisation window:

1. Move the mouse cursor to any edge of the window, the cursor will change to a resizing cursor.
2. Click and drag the window size to the size you want.

To set the response of a visualisation to sound changes:

1. Right-click within the visualisation to display the visualisation pop-up menu.
2. Select Properties.
3. Set the Response slider to the time you want to use between updates of the VU meter.

Note: a smaller time interval will use more CPU time and may slow down other processes within Soundprobe and other applications.

VU Meter

Shows the peak sound level at small intervals in time, enabling you to see how the overall volume envelope of the sound changes over time.

To set the colour for an element of the VU meter:

• Click on the coloured box to the right side of the elements name.

To use a solid bar colour:

• Disable the Gradient Fill check box for the bar colour.

To use a graded bar colour:

• Enable the Gradient Fill check box for the bar colour.

To use a solid background colour:

• Disable the Gradient Fill check box for the background colour.

To use a graded background colour:

• Enable the Gradient Fill check box for the background colour.

To change the style of the VU meter:

• Enable or disable the check box in the Options ground to change the components used on the VU meter.

To set the high and low volume levels:

• Set the High and Low level sliders to the dB level for high and low sound level indication.

To set the drop off time for the bars:

• Set the Drop-Off slider to the time interval you want to use for the bars to drop to zero when the sound level goes to zero.

Light Organ

Shows the intensity of the main three frequency bands as a colour change from black to the set colours for each band. The colours for each band are mixed together to give an overall colour which you see.

To set the colour for a frequency band:

• Click on the coloured box to the right side of the frequency bands name.

To set the drop off time for the colour change:

• Set the Drop-Off slider to the time interval you want to use for the colour change to black when the sound level goes to zero.

To set the lowest intensity shown:

• Set the dB Range slider to the lowest intensity which causes a colour change.

LR-Correlation

Shows the correlation between the left and right channels by using an FFT.

To set the colour of an element of the meter:

• Click on the coloured box to the right side of the elements name.

To set the resolution used for the correlation:

• Set the Resolution slider to the value you want to use for the FFT.

To set the drop off time for the graph:

• Set the Drop-Off slider to the time interval you want to use for the graph to become flat when the correlation becomes zero.

Oscilloscope

Shows the changing sound for a set amount of time over the width of the window.

To set the colour of an element of the scope:

• Click on the coloured box to the right side of the elements name.

To set the time displayed:

• Set the Width slider to the length of time you want to show along the horizontal axis of the oscilloscope.

To set the drawing mode:

• Select a drawing mode from the Draw Mode drop-down list.

To enable or disable axes:

• Enable or disable the Show Axes check box.

To fade the previous scope view:

• Enable the Show History check box.

To wipe the previous scope view:

• Disable the Show History check box.

To set the fade amount:

• Set the Fade slider.

Spectrogram

Shows the frequencies contained within the sound vertically with the intensity of each frequency band being shown as a change in colour. As the frequencies change the spectrogram is scrolled enabling you to see how the frequencies change over time.

To set the colour of an element of the spectrogram:

• Click on the coloured box to the right side of the elements name.

To set the resolution used for the frequency display:

• Set the Resolution slider to the value you want to use for the FFT.

To set the lowest intensity displayed:

• Set the dB Range slider to the lowest intensity you want displayed.

To set the mid-colour position:

• Set the Mid-Colour slider to the percentage for the mid colour.

2D Polygon Frequency

Shows the frequencies contained within the sound horizontally and their intensities vertically.

To set the colour of an element of the frequency display:

• Click on the coloured box to the right side of the elements name.

To set the resolution used for the frequency display:

• Set the Resolution slider to the value you want to use for the FFT.

To set the lowest intensity displayed:

• Set the dB Range slider to the lowest intensity you want displayed.

To set the drop off time for the graph:

• Set the Drop-Off slider to the time interval you want to use for the graph to drop to zero when the intensity becomes zero.

3D Frequency Graph

Shows the frequencies contained within the sound horizontally and their intensities vertically, the graph is scrolled backwards enabling you to see how the frequencies change over time.

To set the colour of an element of the frequency display:

• Click on the coloured box to the right side of the elements name.

To set the resolution used for the frequency display:

• Set the Resolution slider to the value you want to use for the FFT.

To set the lowest intensity displayed:

• Set the dB Range slider to the lowest intensity you want displayed.

To set the drop off time for the graph:

• Set the Drop-Off slider to the time interval you want to use for the bars to graph to zero when the intensity becomes zero.

Spectrum Analyser

Shows the frequencies contained within the sound horizontally and their intensities vertically in a similar fashion to a VU meter.

To set the colour of an element of the frequency display:

• Click on the coloured box to the right side of the elements name.

To set the number of frequency bands:

• Set the Bands slider to the number of bars to display.

To set the lowest intensity displayed:

• Set the dB Range slider to the lowest intensity you want displayed.

To set the drop off time for the graph:

• Set the Drop-Off slider to the time interval you want to use for the bars to drop to zero when the intensity becomes zero.

To display axes:

• Enable the Show Axes check box.

To display solid bars:

• Disable the bars Gradient Fill check box.

To display gradient bars:

• Enable the bars Gradient Fill check box.

To display a solid background:

• Disable the backgrounds Gradient Fill check box.
