LED strip lights linked to a specific sound.

I work in medical simulations and I'm wanting to build a project for one of our tactical medical care courses. We have an audio track that plays as background noise during an exercise (gunfire, shouting, explosions, etc). To further deepen the immersion into the experience I'd like to add some LED's that will flash when there is gunfire on the audio track. I have searched for something similar on Google as well as here and I've come up with a whole lot of programs that will reacted to Christmas music (and one to the BeeGee's) but I haven't found anything that targets a specific sound.

On hand I have the following:
1 Arduino Uno
2 Raspberry Pi3's
1 Raspberry Pi touch screen
2 Utilitech LED strip lights #0709208
1 rather large and extremely loud bluetooth speaker (it belongs to the school so I can't "hack" it)

My question is, where should I begin? I have no formal training in programming. Everything I know I've taught myself, and I could pass on all of my knowledge in the subject in 5 minutes, which would leave 4 mins and 30 sec. to spare. What tree should I start barking up? Thank you for your time!

If that gunfire is much louder than the rest of the noise, a sound detector may do the job. Sometimes called clap detectors as they're mostly picking up sudden loud sounds.

Is it possible to have the Bluetooth stream to multiple clients simultaneously? That may be an avenue of connecting one of your RPi and have it do on the fly sound analyses.

One unrealistic aspect is that the flash will always follow the sound, while in reality the sound follows the flash. That said, modern guns don't produce much if any flash, though grenade/bomb impacts may.
