WizzJ is a cutting-edge music visualizer for high-end iOS devices. It fully exploits the latest advances in graphic processors to create a flow of animated generative art. The animations are synced with the beat and texture of the music being played from your music library. If no music is playing, WizzJ can capture input from the microphone. WizzJ represents a new generation in the art of music visualization! Download WizzJ for free and enjoy a fully functional preview of the available 36 styles, each providing a unique and immersive experience: A Flower of Life, Alien Speak, Ancient Glyphs, Beat Tunnel, Beat'n Chaos, Blossoming, Breeze of Oil, Brick Islands, Color Wand, Cricumpunct, Crystal's World, Dancing Blobs, Disco Sun, Entwined, Girl's Best Friend, Holes of Color, LP's Revenge, Matrix, Neon Ice, Ocean, OneHundredEiiigghtyyyy, Phoenix, Polar Texture, Pop Art Dive, Puzzled, Rainbow's Birth, Sandworms, SpeedBeat, T-Rex's Skin, Tentacles, The Beauty Within, Threads of Light, Threesome, Wanna Kiss?, Wave Dance, Wheel of Color. WizzJ uses Apple's built-in media player and can thus access your existing songs and playlists. In contrast to most other visualizers, WizzJ analyzes the sound of played songs without using the microphone; hence you can enjoy WizzJ even with headsets. Note: Apple does not allow to analyze streamed music. Thus, only music saved on your device and played through the internal iOS audio player is supported. Unfortunately, Apple Music, Spotify et al can therefore not be supported. WizzJ can support the device's native display resolution for a detailed and crystal clear presentation. Activate this feature in the Settings App if you have a powerful device. You can easily create your own music videos by capturing WizzJ's animations with QuickTime and your Mac. Videos and more info can be found on the "Developer Website". Customer comments: ***** Unbelievable Music App "Best music app so far in iTunes Store.

Ferromagnetic: Music Visualizer & VJ App for iPhone, iPad, and Mac Ferromagnetic turns Spotify, SoundCloud, YouTube, and any other sound into stunning real-time visuals. It's a professional audio visualizer for everyone, from home listening and house parties to DJ sets, live shows, and VJ performances. FM Visualizer: Effortless Background Visuals Start a System Broadcast and Ferromagnetic follows the audio of Spotify, SoundCloud, YouTube, and most other apps on your device. Or use the microphone to visualize anything around you, from a DJ set to a live band. The 12-band frequency analysis and tunable beat detection catch every beat and note, and a GPU-accelerated Metal engine renders it all in multiple layers. Pick a Vibe like Calm, Energetic, Trippy, or Retro to set the mood in one tap. Or let Ferromagnetic take the wheel and build new scenes on its own from over 1,000 combinations. Set how fast the scenes change and choose from ten transition styles, including Morph, Zoom, and Color Distance. Choose from over 20 audio-reactive effects: the signature Ferrofluid and Electromagnetic fields, plus Starfield, Petals, Laser, Glitter, Cloud, Refractions, and more. Build your own scene from three effect layers and particles, each with its own blend mode, and tune every layer to the bass or the highs. Particles burst and flow with the sound, and glitch and shake hit harder as the volume rises. Transform the image with Kaleidoscope, Droste Spiral, Voronoi Mirror, or Tunnel, then shape the look with pixelation, dithering, blur, and color palettes like Vivid, Warm, or Triadic. Show your own logo text on screen, perfect for cafes, bars, and venues. Mirror the visuals to a TV or projector with AirPlay or a cable, and the screen stays awake for as long as the music plays. Visuals render at up to 60 fps. FM Producer: Live Visual Performance On iPad, FM Producer turns Ferromagnetic into a VJ app for live shows. The dual-deck interface works like a DJ controller: prepare the next scene on one deck, then crossfade it in. Add the iPad camera or NDI® sources as live layers, and send your visuals to OBS, Resolume, and other apps with NDI output. Connect a MIDI controller or keyboard, map any control with MIDI Learn, and trigger effects and scenes without touching the screen. FM Producer also unlocks the complete Mac app, with video, image, and 3D model layers, presets, and video recording. Try It Free Download Ferromagnetic for free, then unlock only what you need with an affordable subscription or a one-time purchase. One purchase works on iPhone, iPad, and Mac.
