תיאור

MuVis is an open-source macOS & iOS app for music visualization. It renders informative (and musically useful) graphical displays in real time from music files being played - or from the device's microphone. Real-time music visualization is an exciting endeavor - providing the user with dynamic visual and aural stimulation and edification.

When the MuVis app first opens, the on-screen display should look somewhat like the first screenshot shown above and the computer's speakers should be playing music from a pre-loaded royalty-free music file. (Currently, the song file is "The Elevator Bossa Nova" from Bensound.com.) The on-screen display shows a real-time dynamic visual representation of the audio that you are hearing.

Click-and-drag any corner of this window to freely re-size it to any width and height you wish.

The menu bar at the top shows the app's title "MuVis - Music Visualizer" followed by the name "Piano Keyboard" of the particular visualization selected for display. The top and bottom toolbars contains buttons and sliders to allow you to control what you see.

At the bottom left are two buttons labelled by left- and right-chevrons. Clicking the left one changes the display to the previous visualization, and clicking the right one changes the display to the next visualization - which allows you to cycle through the twenty-four visualizations currently provided by the app.

Adjacent to these Visualization chevrons are two Option chevrons. Clicking the downward-pointing one changes the display to the previous option, and clicking the upward-pointing one changes the display to the next option. When programming these visualization algorithms, there are numerous variations and options available to the developer. This button allows the user to select to see any of four variations.

Adjacent to these Option chevrons is a “Pause” button. When clicked, it stops the music playback and freezes the visualization display. The button icon changes to “Play” which, when clicked, causes the music playback and the visualization display to continue.

The adjacent button has a "Microphone" icon. When pressed it stops playing the audio from the selected song file (and also stops it's visualization), and starts playing the live audio from the microphone (and starts it's visualization). The icon then becomes a slashed microphone - which, when pressed, performs the reverse actions and changes the icon back to "Microphone".

The next button has a "Music List" icon. It allows you to select whatever songs you want from your own Music folder. Selecting a song causes that song to play - and the visualization to render its dynamic attributes.

The adjacent button has a “Waveform” icon with a minus sign. When clicked, it passes the audio signal through a “spectral enhancer” filter which reduces the display of noise (usually percussive effects which smear spectral energy over a large frequency range), and enhances the display of spectral lines (usually the harmonics of musical notes).

Finally, at the right end of the bottom toolbar are two buttons labelled UserG (for User Guide) and VisG (for Visualization Guide). Clicking either button activates a “Quick Look” popup window to display the app's documentation.

The top toolbar contains two sliders - one controlling "Visualization Gain" and the other controlling "Visualization Treble Boost". As their names imply, sliding them adjusts the gain and slope of the visual data representation.
