I just bought a LIFX+ light bulb, and the light strip, with the goal of using them for simple music visualization. Not looking for something too complicated - even just flashing or pulsing the light a single color when a certain volume threshold is exceed (I’ll link to a video below) would do - like this good old-school “Sound activated 15 Color LED Light Bulb” from Eagle Light, which is equipped with its own microphone and DSP chip, and which worked great in 2011 when I bought it (sorry I haven’t linked to that bulb - I’m a “new user” and limited to 2 links like an ordinary spammer :-/).
However, I haven’t found any decent real-time music visualization option. On Android, the LIFX app’s Music Visualizer pulses the light completely at random and not in sync with the music, and the LIFX team seems to be aware of this. The iPhone app is better (no random flashing) but not really in sync.
Here’s a video I recorded with what I mean by “in sync” - it’s me manually matching the simple beat of Queen - We Will Rock You:
Is automatic music visualization like this possible to achieve with the LIFX and it’s just a problem of finding or writing a good app?
But keep in mind that the bulb command rate limits still apply. Also the responsiveness of the lights will be better if there are more bulbs that can share the workload. A “spike” on the Visualizer involves 2 commands (turn light on over duration X, turn light off over duration Y), so if you only have 1 Hue bulb for example, the app has to wait until both those commands to finish before it can control the bulb again (which could be as long as 1 second).
