    What you want is called a color organ. Use that as a search term here or in google and you will see many good designs.

    If you need search google for color organ circuit.

    There are standard VU bar integrated circuits that will handle the animation part. If it hears a loud sound, it lights more leds.

    Get searching. When you find a design you want to impliment, post a link here and we can help you adapt it to your leds and component system.

    You bought cheap C****SE LEDs with a very narrow beam angle so they are nearly useless. Wide angle American or British LEDs should be used.
