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 simple sound wave visualizer l needed *2025-01-31* I scoured the internet and searched the App Store for days testing and deleting one app after the next, and nothing worked for my needs, until I discovered MuVis Sound Visualizer. This is a simple use-case for personal use, and I needed to upload audio files (not music just voice audio) and be able to see the sound waves on the screen. No it doesn’t have all the bells and whistles of some other apps but in this case those extras were getting in the way of my simple needs for this project. I love the simplicity, the ease of use, and the additional options in this app to customize the look of the sounds on screen. I haven’t tried yet but I’m hoping to be able to screen record the visuals and then use them in a video. Thanks to the developer(s)! **Developer response:** Thank you very much for the 5-star review and the kind words. ### 5/5 — Very very good! *2024-09-28* Super cool. Love it! **Developer response:** Thank you very much for the 5-star review and the kind words. ### 5/5 — Excellent *2023-03-23, version 2.0* Updated version of this app works perfectly on my MacMini 2020, M1 chip 8GB memory, macOS Ventura 13.2.1., analysing audio from external mike and MP3. It creates interesting visual results from audio, particularly when analysing voice to indicate how vocal harmonic frequencies are affected by the vocal tract resonances. Detailed explanations of the visualisations are available by clicking the VisG button. ### 4/5 — Its simple and easy *2022-09-10* Nice spectrum very pleased This works, many others don't or require additional $$$ **Developer response:** ET Home, I invite you to contact me at kbromley@me.com. I am the developer of MuVis and would love to get feedback from you on how to make it better. Keith ### 5/5 — Surprisingly interesting and intriguing *2022-08-18, version 1.0.3* I've started using your music visualiser. I imagine it being used in public places where music is playing (cafe, restaurant) especially where there is a lot of background noise and it might be a way of connecting people to the music to help them synchronise. I suppose it could also benefit people who are hard of hearing with respect to inclusivity. And I wonder if it could also help with the hard of hearing to learning to dance - to visually see what was happening with the music? Great work! ## Frequently asked questions about MuVis ### What is MuVis?
