MuVis vs FFT Spectrogram Music Player

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. The top and bottom toolbars contains buttons and sliders to allow you to control what you see. Triple-tap your screen to show/hide these toolbars. 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 thirty-four visualizations currently provided by the app. Also, you can simply swipe left or right to change the visualization. Adjacent to these Visualization chevrons are two Option chevrons. When programming these visualization algorithms, there are numerous variations and options available to the developer. These buttons allow the user to select to see any of eight variations. The particular variation rendered is different for each visualization. Also, you can simply swipe up or down to change the option rendered. Adjacent to these Option chevrons is a “Pause” button. When clicked, it stops the music playback and freezes the visualization display. The button label 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 label 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 iCloudDrive 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. The source code for this app is posted at www.github.com/Keith-43

The FFT Spectrogram Music Player is not just a regular audio player, but a powerful tool for the perfectly synchronized and fascinating visualization of sound in real-time. I originally created this app for myself because I love "watching" the music I am listening to. Visualizations reveal so many hidden details in a track, whether it's the vocals, drums, or intricate melodies. I invested a lot of time ensuring the audio and visuals are perfectly in sync. When playing over Bluetooth, you can easily adjust the audio timing in the settings to maintain this perfect synchronization (for reference, I use -250ms when playing directly on my iPhone, and about +100ms for my car stereo). While my personal favorite is the 2D waterfall spectrogram, I have also added stunning, interactive 3D visualizations to offer even more variety. You can fully control the camera using touch gestures—just play around and explore! If you are missing a feature or have any feedback or wishes, feel free to drop me an email. Whether you are an audiophile, a musician, or just a fan of breathtaking visual effects – this app precisely analyzes the frequencies of your music and displays them seamlessly. Main Features: • Spectrum Analyzer: High-resolution stereo display (Left/Right) with 512 frequency bands for detailed frequency analysis. • Waterfall Chart: Track the acoustic history of the last 3.0 seconds in a breathtaking, color-coded waterfall graph. • 3D visualizations, customizable with drag and pinch gestures (with one finger: drag - and two fingers: rotate - Mac: click/drag: move camera left/right/up/down; shift and click: rotate, pinch to zoom) • Real-Time Sync: The visualizations react to the beat and frequencies of the music without any noticeable lag. • Built-in Player & Playlists: Manage and play your favorite music directly within the app. • Microphone Input: Use your iPhone's microphone to visualize ambient sounds, live music, or your own voice in real-time. Free Version & Pro Upgrade: You can download and try the FFT Spectogram Music Player for free. Please note that the diagrams in the free version feature a subtle watermark. Love the app? Unlock the Pro version with a one-time in-app purchase for just $0.99 (0,99 €)! The upgrade permanently removes all watermarks, allowing you to enjoy the pure, unclouded visualization of your music.
