Get your party pulsing with this new app from Stratospherix. PartyPulse responds to the music that your iPad or iPhone hears and converts it into a multi-coloured light show. Select colours, shapes and movement styles to match the mood, turn the lights down and the music up. Use the camera to create new images for the show. The best bit is that you can AirPlay to AppleTV or connect your iPad to a TV via a video cable to make the effect go large, dimming the screen on the device to keep the party going longer. Have ideas for new shapes and options? Let us know via @stratospherix or support@stratospherix.com. Note that PartyPulse listens for ambient music for its light show - you’ll need something else to play music on!

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.
