I created a free, open-source, low-latency focused music visualiser and lighting controller for DJs (For Android devices)
I use Traktor for live mixes, and use both visualizers and room lighting to accompany my sets.
This application I've built is primarily a music visualiser, but can also control room lighting and sync to the music.
Unlike many android based visualisers, this one has a specific focus on low-latency and uses a low-level C++ audio engine for sub-10ms mic latency, which means it reacts instantly.
It supports Ableton Link over Wi-Fi so you can lock the visual effects directly to Traktor, Live, or Serato. The mic drives the textures, while Link synchronizes the beat grid. And it will also sync up Philips Hue, Lifx and Nanoleaf panels with minimal latency. I'm also working on a WLED (ESP32) and Govee lighting integration.
I've been using it with my setup, and the light syncing works much better for me than the official applications from Philips hue or Lifx.
It's not in production in the playstore yet, but if anyone is interested in trying it out, I'll include some links in the comments so folk can add themselves to the early access test .
Feel free to run it with your DJ software and let me know how it goes. Or - just have a look at the visualisers and let me know if you have any feedback.
Oh and this is completely free, ad-free, and open-source. I built it purely out of my own interest and desire to create an actually reactive audio visualiser and room lighting controller.
Cheers!
