=Waveform=

==Overview==

The Waveform add-in allows for the creation of a graphical representation of the amplitude of the soundtrack attached to a sequence. This can be in the form of either a single channel that has the cell intensity vary with the amplitude. Or a bar-graph style display using a range of channels.

[[Image:Waveform_00.jpg]]

==Components of Waveform add-in==

[[Image:Waveform_01.jpg]]

Waveform add-in screen

===Waveform representation===

These are the options for the mode of operation of the waveform add-in.

====On/Off over channel range====

[[Image:Waveform_03.jpg]]

This is the option that generates a bar graph style representation of the amplitude of the soundtrack associated with the sequence. The intensity of the of the individual cells in the bar graph are set to 100%.

====Dimmed values in single channel====

[[Image:Waveform_04.jpg]]

This is the option that as its name implies uses a single channel that contains cells of varying intensity corresponding to the amplitude of the soundtrack.

===Channel selection===

This is where you select the channel(s) to use with the waveform display.

[[Image:Waveform_02.jpg]]

When selecting a range of channels for use with the On/Off values option, those channels must be in a single block. If you skip any channels the add-in will only work with the first group of channels it sees and will ignore the remainder you have selected.

The Dimmed values option will only allow you to select a single channel.

===Auto scale===

[[Image:Waveform_06.jpg]]

Selecting auto scale means that the add-in will ensure that only loudest sections of the soundtrack will be set 100% intensity for Dimmed value mode, or all channels of the range mode will be on.

===Scale factor===

[[Image:Waveform_05.jpg]]

When auto-scale is not selected the scale factor can be manually adjusted.

[[Image:Waveform_08.jpg]]

The above series of screen shots shows the audio visualiser representation of a section of the soundtrack attached to a sequence and the corresponding outputs from the waveform add-in. Firstly with auto scale selected, secondly a small scale factor entered, and finally with a large scale factor entered.

==Completing the process==

[[Image:Waveform_07.jpg]]

Once you have made your choices, click on the start button and the add-in will write data into the selected channel(s).

==Advanced programming tips==

===Dimming bar graph===

[[Image:Waveform_09.jpg]]

The cells of the bar graph waveform display are created at 100% intensity. By combining the dimming display with the bar graph display you can create a dimming bar graph.

To do this you need to create both the dimming and the bar graph displays. Select and copy the channel containing the dimming display. Then Paste Boolean AND that information over each of the channels of the bar graph display ( as shown above).

===Peak bar graph===

[[Image:Waveform_10.jpg]]

Comparison of standard bar graph to peak bar graph (note: shown vertically mirrored for clarity)

The bar graph that is produced by the waveform add-in is a solid bar graph. This can be converted to a display where only the top most cell of the bar is displayed.

[[Image:Waveform_11.jpg]]

As shown in the image above, select and copy the row 2 information. Then select row 1 and use the Paste Boolean XOR function to overwrite row 1. Make sure the column you start the copy from is the same column you paste to.

[[Image:Waveform_12.jpg]]

In the image above you can see that cells in row 1 have now been set to 0% where they are beneath cells in row 2 that are at 100%.

Next select and copy row 3 and use Paste Boolean XOR to overwrite row 2.

[[Image:Waveform_13.jpg]]

In the image above row 2 has now been converted.

Continue the process. Copy row 4 and paste boolean XOR with row 3. In the example shown, the process concludes when eventually row 7 is copied and boolean XOR pasted to row 6.

[[Image:Waveform_14.jpg]]

The final result.

===Taking it further===

You can combine the procedures to create composite displays. For example, a peak display superimposed over a standard bar graph (that has been reduced in intensity).

Prof: added more info

[[Category:Vixen]]
=Frequency Spectrum Add-in=
==Overview==
*The Frequency Spectrum add-in splits the audio soundtrack of the sequence into frequency bands.
*These bands are linked to channels in the sequence.
*The add-in examines the soundtrack.
*The Scale and sliders are adjusted to set the threshold for the add-in.
*If the amplitude of a frequency band reaches the threshold point then the cells of the linked channels where this occurs are set to 100% intensity. Cells that were not set by the add-in retain their original value.

==Components of Frequency Spectrum Add-in==
[[Image:Spectrum_01.jpg]]

Frequency Spectrum add-in screen

===Frequency Bands===
[[Image:Spectrum_02.jpg]]

The audio is split into 31 bands ranging from 20Hz up to 20kHz. When you play the sound track a bar graph showing the amplitude of that frequency is displayed in the black rectangle. The lower portion of the bar graph is Green, with the mid an upper sections appearing as Yellow and Red respectively. The height of the bar graph is affected by the Scale setting.

===Channel Indicators===
[[Image:Spectrum_03.jpg]]

The channels in the sequence are shown as a row of squares below the frequency band. If there are more channels than can be displayed in the window then there will be scroll arrows visible to indicate that more channels are available. Click on the arrow to display these channels. Hovering the mouse pointer over a channel indicator will display the channel name.
===Auto Mapping channels===
[[Image:Spectrum_04.jpg]]

The channels can be automatically mapped. Click on the Auto Map button to display the auto map options screen. With auto mapping you need to have 31 consecutive channels available if all frequency bands are used.

[[Image:Spectrum_05.jpg]]

The first channel in the sequence and the first frequency band are displayed when the auto map window is initially displayed.

*From the Start channel drop down list select the first channel to be used by the add-in.
*From the Start band drop down list select the first frequency band that you want to utilize. Any frequency bands below the selected start band will be ignored.
*Click on the OK button to map the channels. The frequency bands will then be individually mapped onto consecutive channels according to the choices you have made.

[[Image:Spectrum_06.jpg]]

===Manually Mapping Channels===
Manually mapping the channels allows you to be more selective and creative with the channel mapping when compared to auto mapping.

[[Image:Spectrum_07.jpg]]

In the example shown above you can see a frequency band linked to a single channel, a group of frequencies linked to a single channel and a single frequency band linked to multiple channels. More complex linkages can be achieved than has been shown.

*To link a frequency band to a channel, position the cursor over the black area of the frequency band and drag the cursor over to the desired channel. When the mouse button is released the link will be created. Or it can be done in the reverse direction by dragging from the channel indicator to the frequency band.

*To break a link drag the White marker (at the top of the link connecting line) into any white space outside of the black area. Or by dragging the Black marker (at the bottom of the link connecting line) into any white space outside of the channel indicators.

*To move a link simply drag a marker to the desired location. When you move a link from one frequency band into another band already containing a link, then the link you are moving will replace that link.
*To link a frequency band to multiple channels simply drag from the black area of the desired frequency band to as many channels as required.
[[Image:Spectrum_08.jpg]]

*To link a channel to multiple frequency bands requires an intermediate step. Once the first link to a channel is made, the add-in will not let you directly link additional frequency bands to that same channel. You must first create links to separate channels.

[[Image:Spectrum_09.jpg]]

Then drag the links to the desired channel.

[[Image:Spectrum_10.jpg]]

===Play===

[[Image:Spectrum_11.jpg]]

The frequency spectrum add-in only has simple Play, Pause and Stop functions.

When you play the sound track, bar graphs of the amplitude for each of the frequency bands are displayed within the black rectangles. The lower portion of the bar graph is Green, with the mid an upper sections appearing as Yellow and Red respectively. The height of the bar graph is affected by the Scale setting.

===Scale===

The scale factor is used to adjust the virtual amplitude of the sound track within the add-in. If the scale value is low (initial default is x 1.0) then only the loudest portions of the sound track will reach the threshold. As the scale value is increased then more of the sound track will reach the threshold.

[[Image:Spectrum_12.jpg]]

To change the scale click on the Up and Down buttons. The scale value is displayed beneath the buttons.

===Threshold Sliders===

[[Image:Spectrum_13.jpg]]

The sliders are used to adjust the threshold set point for the add-in.

By default the sliders are automatically adjusted when adjusting the scale.

[[Image:Spectrum_14.jpg]]

If the option is not ticked then the slider positions do not change when the scale is changed.

The sliders can be manually adjusted even if auto adjust is ticked. To adjust the sliders position the mouse cursor over the blue slider ( the cursor changes to a double arrow) and drag the slider to the required position.

[[Image:Spectrum_15.jpg]]

The higher the slider is set then the higher the threshold is and the louder the sound track within that frequency band needs to be to reach the threshold. And conversely the lower the slider position, the lower the threshold and the quieter the sound track within that frequency band needs to be to reach the threshold.

==Completing the process==

Clicking on the OK button will commence the analysis of the soundtrack.

[[Image:Spectrum_16.jpg]]

When the amplitude of a frequency band reaches the threshold then any channels that are linked to that frequency band will have those cells in the sequence (where this occurs) set to 100% intensity. Cells that were not set by the add-in retain their original value.

[[Image:Spectrum_17.jpg]]

The above example shows the end result. A low scale value has been used, showing the add-in being triggered by the louder sections of the soundtrack but not responding to the quieter sections.

When you play the sound track, bar graphs of the amplitude for each of the frequency bands are displayed within the black rectangles. The lower portion of the bar graph is Green, with the mid an upper sections appearing as Yellow and Red respectively. The height of the bar graph is affected by the Scale setting.

====Scale====

The scale factor is used to adjust the virtual amplitude of the sound track within the add-in. If the scale value is low (initial default is x 1.0) then only the loudest portions of the sound track will reach the threshold. As the scale value is increased then more of the sound track will reach the threshold.

To change the scale click on the Up and Down buttons. The scale value is displayed beneath the buttons.

====Threshold Sliders====

[[Image:Spectrum_13.jpg]]

The sliders are used to adjust the threshold set point for the add-in.

By default the sliders are automatically adjusted when adjusting the scale.

[[Image:Spectrum_14.jpg]]

If the option is not ticked then the slider positions do not change when the scale is changed.

The sliders can be manually adjusted even if auto adjust is ticked. To adjust the sliders position the mouse cursor over the blue slider ( the cursor changes to a double arrow) and drag the slider to the required position.

[[Image:Spectrum_15.jpg]]

The higher the slider is set then the higher the threshold is and the louder the sound track within that frequency band needs to be to reach the threshold. And conversely the lower the slider position, the lower the threshold and the quieter the sound track within that frequency band needs to be to reach the threshold.

'''Color Organ '''

Is there any information for an add-in to provide a color organ response to a musical selection, similar to the waveform add-in except it separates the audio in to 3 or more individual channels based on frequency. If anyone or a group are interested in working on this, here is the place to document it

==Frequency Spectrum==
===Overview===
*The Frequency Spectrum add-in splits the audio soundtrack of the sequence into frequency bands.
*These bands are linked to channels in the sequence.
*The add-in examines the soundtrack.
*The Scale and sliders are adjusted to set the threshold for the add-in.
*If the amplitude of a frequency band reaches the threshold point then the cells of the linked channels where this occurs are set to 100% intensity. Cells that were not set by the add-in retain their original value.

===Components of Frequency Spectrum Add-in===

Frequency Spectrum add-in screen

====Frequency Bands====
[[Image:Spectrum_02.jpg]]

The audio is split into 31 bands ranging from 20Hz up to 20kHz. When you play the sound track a bar graph showing the amplitude of that frequency is displayed in the black rectangle. The lower portion of the bar graph is Green, with the mid an upper sections appearing as Yellow and Red respectively. The height of the bar graph is affected by the Scale setting.

====Channel Indicators====
[[Image:Spectrum_03.jpg]]

The channels in the sequence are shown as a row of squares below the frequency band. If there are more channels than can be displayed in the window then there will be scroll arrows visible to indicate that more channels are available. Click on the arrow to display these channels. Hovering the mouse pointer over a channel indicator will display the channel name.
====Auto Mapping channels====
[[Image:Spectrum_04.jpg]]

The channels can be automatically mapped. Click on the Auto Map button to display the auto map options screen. With auto mapping you need to have 31 consecutive channels available if all frequency bands are used.

[[Image:Spectrum_05.jpg]]

The first channel in the sequence and the first frequency band are displayed when the auto map window is initially displayed.

*From the Start channel drop down list select the first channel to be used by the add-in.
*From the Start band drop down list select the first frequency band that you want to utilize. Any frequency bands below the selected start band will be ignored.
*Click on the OK button to map the channels. The frequency bands will then be individually mapped onto consecutive channels according to the choices you have made.

[[Image:Spectrum_06.jpg]]

====Manually Mapping Channels====
Manually mapping the channels allows you to be more selective and creative with the channel mapping when compared to auto mapping.

[[Image:Spectrum_07.jpg]]

In the example shown above you can see a frequency band linked to a single channel, a group of frequencies linked to a single channel and a single frequency band linked to multiple channels. More complex linkages can be achieved than has been shown.

*To link a frequency band to a channel, position the cursor over the black area of the frequency band and drag the cursor over to the desired channel. When the mouse button is released the link will be created. Or it can be done in the reverse direction by dragging from the channel indicator to the frequency band.

*To break a link drag the White marker (at the top of the link connecting line) into any white space outside of the black area. Or by dragging the Black marker (at the bottom of the link connecting line) into any white space outside of the channel indicators.

*To move a link simply drag a marker to the desired location. When you move a link from one frequency band into another band already containing a link, then the link you are moving will replace that link.
*To link a frequency band to multiple channels simply drag from the black area of the desired frequency band to as many channels as required.
[[Image:Spectrum_08.jpg]]

*To link a channel to multiple frequency bands requires an intermediate step. Once the first link to a channel is made, the add-in will not let you directly link additional frequency bands to that same channel. You must first create links to separate channels.

[[Image:Spectrum_09.jpg]]

Then drag the links to the desired channel.

The higher the slider is set then the higher the threshold is and the louder the sound track within that frequency band needs to be to reach the threshold. And conversely the lower the slider position, the lower the threshold and the quieter the sound track within that frequency band needs to be to reach the threshold.
