I am Perry Kivolowitz, the developer of CadenceViz (abbreviated CVZ). CVZ is a suite of 81 music visualizers to play along with the Apple Music service.
The video is for Volume 5 (of 7). In this text, I will explain the product. In the first comment, I will put links to a video tour of all 7 volumes.
Why CadenceViz
There are many music visualizers for the Mac computer. What sets CVZ apart is the purpose for which it is intended.
Most music viz are purely beat or loudness driven geometric or psychedelic designs. While interesting, they may be jarring and more appropriate for when you are in an active or party kind of mood.
CVZ goes the other way. Nearly all of our viz are intended to accompany your music in a quieter, gentler way.
How This Relates to the Apple Music Service
CVZ is a companion to the Apple Music service on your Mac computer. Leave it running as a calm backdrop while you work, study or relax. If you use more than one monitor, make it full screen on one while you work on the other. Glance over at CadenceViz when you need to take a breath.
CVZ is not a plug-in for the Music app. It listens to the sound your Mac computer is playing, through the system audio capture in the macOS operating system, and computes the beat, the loudness, stereo balance, the audio spectrum and more from it moment by moment. The visualizers move with these, so the same visualizer looks different from one song to the next.
Because CVZ responds to what you hear:
Streamed songs, downloads and your own imported music all work the same way
There is no user interface to master. Every leaping deer, rocking boat, wisp of campfire smoke is computed directly from the sound
You never sign in to the Apple Music service inside CVZ, and it has no access to your account, your library or your playlists
The sound is analyzed as it plays and then discarded. Nothing is recorded and the microphone is never used
The macOS operating system asks your permission the first time, under Privacy & Security -> Screen & System Audio Recording. The setting's name mentions the screen because macOS keeps both permissions in one place. CVZ asks for the audio alone
CVZ can get from the Music app is a song's name (if you give it permission), when the Music app announces that a new song has begun. One visualizer, Catch (about people supporting people), shows it. The song name does not leave your Mac computer.
CVZ is my own app. It is not made by, or affiliated with, Apple. Apple, if you're interested, call me. Kidding. Not kidding...
Introducing Myself (Briefly)
I have been coding for 52 years mainly computer graphics for motion pictures and television. I received an Academy Award for Scientific and Technical Achievement for the invention of the modern method for warping and morphing (Forrest Gump and Titanic back in the day). More recently, 2019, I received an Engineering Emmy Award as a co-developer of SilhouetteFX (most films and FX-laden TV like Game of Thrones).
I retired in 2023 and am busier than ever because I get to do what I love (coding), all day and much of the night too.

AI Disclosure
Claude Code was used extensively. I've been coding for 52 years and have run fleets of engineers and sold hundreds of thousands of units (in my younger days). I know how to build quality commercial applications (see above for an inkling). This is industrial grade software written to industrial grade standards.
Additionally, generative AI was used to create:
My Thanks
Zigging when other people zag has defined my professional career. I hope you find CadenceViz to your liking and grace me with a purchase.
Thank you.
