Vizual: An audio program and visualizer.

Here is my new audio program built around my visualizer.

Features included so far:
-Visualizes audio (microphone input when song paused, sound card output
when song playing)
-Graphic clock (hover to expand, click and hold to view digital clock)
-Play/pause button (and keyboard control)
-Song progress bar
-Song navigation via progress bar and keyboard control
-Variable afterglow effect
-Ability to select audio files to play from within Vizual
-Graphic indicators of the peak amplitude and average amplitude of the
left and right speakers with each frame

Prioritized features still to come:
-Frequency-based visualizer mode/icon

This Update:
-Added ability to select audio files to play from within Vizual
-Added variable afterglow effect (controlled by slider)
-Altered clock brightness slider to look more appropriate to the
program. I plan to make this a permanent feature.
-Added graphic indicators of the peak amplitude and average amplitude
of the left and right speakers with each frame
-Removed all additional audio files from data folder (files now
selectable via in-program button)

May 21st, 2014 9:00pm Update:
-Added ability to navigate song via progress bar. Click on a point on
the progress bar to jump to that time in the song.
-Added limited keyboard control. Press 'space' to play/pause song
(present since previous update but undocumented). Press right and left
arrow keys to jump 5 seconds forwards and backwards respectively.
-Fixed bug where clock brightness slider didn't move as you rescaled
the window.

May 21, 2014 10:00am Update:
-Fixed mouse detection around play/pause button. Entire circle now
clickable.
-Added manual clock brightness adjustment while program is running.
Drag the slider to adjust the graphic clock's passive brightness, and
press 'm' to print out the opacity value when you think it's just
right. Please email me the printed value so that I can incorporate your
feedback.
