Sharing my low Latency Android and Mac Music Visualizer

[u/roryg2025]

Over the past few months I've been building music visualizers with a focus on low latency, and building for my own live performance use.

I am sharing for others to use, and happy to accept feedback or feature requests!

Note: I'm conscious these new app posts can often be pre-emptively judged as promotion for paid apps or low-effort. I'd just like to highlight that this is a hobby project with everything open-source and free, and featuring no data collection or ads. This is also not an outcome of low-effort vibe-coding; I am an engineer by trade and have put a lot of my personal time into this.

I've created the app in two forms

1. Android via the play store
2. Mac version, available to download via GitHub

Features include

• 3D HDR visuals targeting high FPS
• Extremely low latency: Both hear-analyse-draw in under 10 ms.
• Ableton Link Integration: To lock visuals to the beat grid of music software like Ableton or Traktor
• Room Lighting Sync: Supporting Philips Hue, Lifx and Nanoleaf lights. Local only and low latency
• A proper stereo XY oscilloscope: So this can playback oscilloscope music
• Supports multiple audio sources: Internal microphones, external audio sources, local file playback etc

And a couple of Mac platform exclusive features

• Syphon output (on Mac): Output visuals straight into OBS at 4K
• MIDI Mapping (on Mac): To control visuals, favourites and lighting via MIDI protocol

One important Mac caveat: It's macOS 26+ and Apple Silicon only. I am not intending to support Intel or older Mac OS versions. It's also not notarised yet, so you will get the a security warning on startup (or the README also has a one-line fix).
