QSSP Component v2.0

QSSP QuickTime Component 2.0

OVERVIEW
Audio visualizations are new visual track types added to QuickTime via Totally Hip’s new Spectrograph components. These visualizations allow the multimedia author to visually display audio in their movies. There are three visualization types: Spectrogram, Waveform, and Spectrum Analyzer. Any number of these tracks can be present in a movie and can be configured in a variety of ways. Creating these tracks is as simple as selecting one of these tracks from LiveStage’s New Track menu. Once created, you can then configure the track to appear as you like. The Audio Visualizations components were developed by Totally Hip Technologies Inc. for the Cornell Lab of Ornithology - Macaulay Library & Bioacoustics Research Program.

SPECTROGRAM
The Spectrogram track shows a frequency versus time view of the audio. The color of each pixel represents the energy level of the audio at that point in the graph. You can change the color scheme from the default grey scale to any scheme you want. You can also configure the axes, grid, and play head. The spectrogram will be calculated in real time and will scroll as your sound plays. You can also configure it to show as little or as much as you want of the source audio.


WAVEFORM
The Waveform track shows an energy level versus time view of the audio. This is how most people have seen audio represented. You can change the color of the waveform as well as the color of its background. The waveform is rendered in real time and will scroll as your sound plays. You can also configure it to show as little or as much as you want. As you zoom in to more closely inspect the waveform, it will automatically alter the way it is drawn to show you the most information.


SPECTRUM ANALYZER
The Spectrum Analyzer shows the energy level of various frequency bands at the current instant in time. This can be configured as a bar graph or as an iTunes® like visualization. You can see the most basic bar graph mode at the right. You can customize this bar graph by adding images for each bar and by doing so, create displays like those seen in iTunes. There is a third display mode that allows you to create a visualization that rotates, zooms and fades as the sound plays.


WIRED ACTIONS
Many new wired actions have been added that support the audio visualizations. These wired actions let you control all of the settings of the audio visualization tracks. Using these wired actions you can create your own UI as a part of your wired movie to control the visualization. You can create buttons in your wired movie that preset many settings at once to create different themes for your visualization. For scientific studies you can add buttons that allow the user to fine tune all the parameters that affect the visual output in order to more clearly see the information desired.

NOTES
Annotations can be added to both the spectrogram and waveform visualizations. Notes highlight a portion of the sound in both time and frequency. These notes can be any color and have any meta data desired associated with them. Text captions can be positioned at a variety of places around the note. The authoring of notes can be done interactively by the user or they can be done through XML. Notes also have event handlers, such as mouse click, that can have scripts added to them so that actions can be taken when a note is clicked on or moused over.
