    Nostalgia on Tap

    This really brings me back to listening to vinyl on my father’s stereo system… A masterclass in apps that JUST. WORK. Thank you.

    Makes music fun to watch again!

    LaZ Visual Audio Equalizer is one of those rare apps that does exactly what it promises while also being far more entertaining than you expect.

    The visualizer I didn’t know I needed

    I’ve never had an audio visualizer and to be honest I didn’t know I needed one until I got this. If you’re looking for the best app to visualize sound, you’ve found it with the LaZ Visual Audio Equalizer.

    Heckin’ Sweet

    The simplicity of this app is probably my favorite thing. No calibration required, just turn it on and go. Interface was intuitive without over explaining. Gorgeous and highly reactive visuals.

    I know it’s not really a feature, but I sneezed near it once and it was fun to watch the analyzers max out. 😝

The good kind of tweakable

Dial in exactly the right amount of ridiculous.

Tune sensitivity and VU Drama. Add Jiggle when the music needs more movement. Switch on CHONK-O-VIZ™ for oversized spectrum blocks, pick your own colors, and optionally keep the screen awake for longer listening sessions.

Made for where music happens

Make it part of the listening ritual.

Drop the needle, set your iPhone beside the speakers, and watch the meters bring your turntable setup to life. If the mic can hear the music, LaZ can make it move.

01

Turntables and stereos

Give record rooms, receivers, and speaker stacks the glowing display they deserve.

02

AirPlay and Bluetooth

Stream to a nearby speaker while LaZ listens to the room through your iPhone mic.

03

Concerts and festivals

Bring a pocket-sized wall of meters anywhere the stage is loud enough to hear.

04

Parties and DJ booths

Add motion to house parties, backyard hangs, and late-night listening sessions.

05

Garages and car meets

Pair retro visuals with the stereo setups, old dashboards, and machines that inspired them.

06

Wherever the room moves

No special music service needed. Just put your iPhone near the sound and let it listen.

How it hears the music

Nearly any player works when the room can hear it.

LaZ listens through your iPhone microphone. It does not tap protected audio directly from Apple Music, Spotify, YouTube, or other apps. Send that music to a nearby speaker, stereo, TV, or receiver, and let the room do the rest.

Works great

AirPlay and Bluetooth speakers

Keep LaZ open while music plays through a nearby AirPlay or Bluetooth speaker. Put the phone where its microphone can hear the room, and the visuals respond.

Any player, really

Apple Music, Spotify, YouTube, Sirius XM, and more

The source app does not matter when the music is playing through speakers the iPhone mic can hear. LaZ visualizes the sound in the room, not data from the player.

Not supported

CarPlay, headphones, and the iPhone speaker

CarPlay playback, wired or Bluetooth headphones, and music playing through the iPhone's own speaker are not supported. Use a nearby external speaker, stereo, TV, or receiver instead.

LaZ Player now playing screen with album art and playback controls

In development

LaZ Player is almost ready!

LaZ Player is a dedicated local and cloud music player with these same visual screens built in, so visuals can be driven by the player itself instead of only by the microphone. Adjustable EQs that auto-load depending on which speaker you're playing to. Top 8, CarPlay integration, and much more!

For the noisy stuff

Jeep Mode tames the rumble.

When wind, road noise, fans, and other environmental sound hit the microphone, Jeep Mode adds adjustable filtering so the display can stay responsive to the music instead of overreacting to low-frequency noise.

Wind DSP

Adjust filtering for wind and road rumble.

Bass Keep

Reduce or preserve low-end energy in noisy environments.

Jiggliness

Control how much extra movement the visualizer adds.

Woo!

Does absolutely nothing. Still important.

Your mic. Your music. Your phone.

No signup. No tracking. No subscription.

Open it, set your iPhone near the sound, and watch the room come alive. There is no account to create and no personal data to hand over.

No data collection: LaZ Visual EQ does not collect your personal data or track what you listen to.

No recording: audio is analyzed in real time and is not saved by LaZ Visual EQ.

No uploading: audio never goes to a server and never leaves your phone.

Mic shuts off: the app stops listening when it closes or goes to the background.
