I'm not sure what I want to do it actually possible in App Inventor as I have been unable to find any examples.
What I want to do is play a sound file but then have the app react to the sound its playing.
The plan would be that the app would be controlling some leds that would change colour, brightness in time with the sound.
I can already do the led control its just the part about getting the app ti be able to hear whats its playing and convert that into some value.

That sounds hard.
Consider simulating a player piano, with multiple channels in parallel,
each controlling an LED or sound, in lock step.
Search the Internet for the MIDI message data stream
for a way to encode a performance for your device.
