There's another approach, what about controlling the LEDs with the pitch of the sound.
You can do it like this. Get an electrolytic microphone. connect it with A0 pin of Arduino(any board). then use the library open music lab
,it consists of FHT library which perfectly samples the incoming signals and puts them into different frequency bins and then uses Fourier Hartley Transform to sample the signal into different frequency bands.
so you can program your Arduino using this library in such a way that different colors glow at different frequency bands.
Next step is controlling LED strip from Arduino. For this, you can use IRL540(recommended) or IRF530 for better current amplification and switching. You can also use this module https://shop.controleverything.com/products/8-channel-8w-open-collector-fet-driver
