Make the music visible, and turn your iPhone or iPad into the retro audio display your stereo deserves. LaZ Visual Audio Equalizer is now LaZ Viz Audio Visualizer. The name has changed; the free v2.0 upgrade brings more ways to see your music. LaZ Viz listens through your device's microphone and turns the sound around you into dancing spectrum lights, moving needles, glowing waves and whole worlds that come alive with the music. Version 2.0 brings rebuilt audio analysis, refreshed VU and McVU meters, native iPad layouts and layouts designed for iPhone Duo from day one. Made for Duo: Open, fold and rotate with layouts that follow the space available. VU meters can occupy separate fold regions. Phosphor keeps its round scope and controls within reach. Partially fold Duo in Jeep Beach for a dedicated JUMP panel alongside the scene. Meet the new screens: • Dairy Freefall: six evolving looks, including Light Tunnel, electric arcs, neon ropes, kaleidoscope, double helix and a pulsing logo vortex. Import your own logo from Photos or Files, choose its color mode and adjust transparency. • Aftershock: a neon spectrum landscape beneath a synthwave sunset. • Oceanic: rolling water, reflected light and interactive splashes. • Jeep Beach: a pixel-art beach ride that bounces along with the music, framed by a nostalgic bedroom TV. Tune in, hit the beach and add a little extra jump. • Block Monster: glossy stacks, falling peak caps and a city loft setting. • Phosphor on iPad and iPhone Duo: a green-glowing oscilloscope with adjustable intensity, focus, gain and timebase. • 2002: a second interactive car stereo, with four live displays, dolphin and racing animations, a folding faceplate, an ejectable CD and haptics on supported devices. The originals are still here: Classic Viz, Blue Da Ba Dee, Custom Viz, VU, McVU, Vox and the interactive 1995 stereo with eight presets, working controls, a moving CD, haptics on supported devices and hidden surprises. CHONK-O-VIZ turns the classic spectrum grids into oversized blocks. Custom Viz lets you choose the bottom, middle, top and falling peak colors. The 1995 screen keeps its original LaZ EQ branding as a tribute to the fallen. Make it feel right: In portrait, open Settings to adjust Sensitivity, VU Drama, Jiggle and your colors. Try experimental Jeep Mode to tame wind, road noise, fans and other low rumble. Swipe between screens, use the portrait picker to jump to a favorite, and tap to embiggen. Keep the screen awake for long listening sessions. Made for the music around you: Put it beside a turntable, stream to a nearby AirPlay or Bluetooth speaker, or bring it to concerts, festivals, parties, DJ sets, garages and car meets. Microphone access is required for live sound response. LaZ Viz visualizes audio rather than changing it. It cannot read protected audio inside other apps, and it does not work with CarPlay or music played through your device's own speakers. It is an entertainment app, not a professional analyzer or calibration tool. Your microphone audio stays on your device. It is processed live, never recorded, saved or uploaded. The orange microphone dot is expected while the meters are active; capture stops when the app closes or enters the background. Optional major-update reminders are local and can be turned off anytime. Delivery depends on iOS background availability. Already own version 1? Version 2.0 is a free upgrade. No subscription. No signup. No tracking. Just music you can see.
