Setup questions
Do I need to install software?
No. Just open app.autovj.club in Chrome and the demo is ready to test. No installation or sign-up required.
Can I operate it from a phone only?
The main output should still come from a PC, but day-to-day controls work from a phone. Sign in with the same Google account on both and they stay in sync.
Does it work on Mac and Windows?
Both. Note that older Intel Macs with integrated graphics can drop frame rate in fullscreen. Apple Silicon (M1 and later) is stable.
Is internet required?
Yes. YouTube playback, lyrics, and song recognition (ACRCloud) all need network access. Aim for 10Mbps+ downstream, ideally wired, or a venue-only 5GHz Wi-Fi.
What happens on an unstable connection?
YouTube playback stalls, lyrics lag. Sharing bandwidth with customer Wi-Fi is the most common cause of sudden freezes on busy nights.
How can I improve song recognition?
Mic placement is 90 percent of the answer. Place the mic within 1 to 2 meters of a speaker, away from HVAC, and the 60-second default Auto Identify hits 70 percent or higher.
Should I shorten the recognition interval?
No. Dropping below 60 seconds barely changes hit rate but roughly quadruples ACRCloud cost. 60 seconds is the tested sweet spot.
What kind of computer is recommended?
Any machine that runs Chrome smoothly: 4+ cores, 8GB RAM, and ideally a discrete GPU or Apple Silicon. Avoid older integrated-GPU Intel Macs — they fall back to SwiftShader.
Can I drive multiple screens?
Mirroring to copies works out of the box. For different content per screen, use separate PCs and browser instances. Start with a single reliable path and grow from there.
Which mic should I buy?
A USB condenser mic in the low-tens-of-dollars range is plenty. Built-in mics work for testing; a USB mic near the DJ booth improves hit rate noticeably.
Does it run on iPad?
The control page (/control) works. The main output surface should still be desktop Chrome — iPad Safari + WebGL has enough constraints that we do not recommend it for primary visuals.
