TL;DR

Dirty Pool Pinball builds live-triggered soundtrack system for Shadow machine using contact microphones.

Summary

Jeff from Dirty Pool Pinball demonstrates a creative sound design experiment using piezo contact microphones attached to a Shadow pinball machine's playfield. The microphones capture vibrations from ball movement and trigger sounds in real-time, creating a dynamic, evolving soundtrack generated live during gameplay. The project was inspired by a French installation artwork involving birds triggering sound events.

Key Claims

Piezo contact microphones are attached underneath the playfield of a Shadow pinball machine to capture vibrations
high confidence · Jeff from Dirty Pool Pinball demonstrates the hardware setup and functionality on his Shadow machine
All sounds are generated in real-time during gameplay, not added in post-production
high confidence · Jeff explicitly states: 'everything you're hearing right now when this happens and I pull this trigger uh is in real time. It's not being done in post. It's being generated live uh as we play.'
The sound system uses multiple layers that can be modulated in different ways based on pinball events
high confidence · Jeff describes setting up 'multiple layers of sound layers that are triggered by these events' with modulation capabilities
The concept was inspired by a French installation artwork by an artist named Amadeay involving birds triggering sound events
medium confidence · Jeff references watching a video of this concept and deciding to apply it to pinball machines
The sound setup could potentially be reconfigured to trigger drum instruments, creating a drum machine out of the pinball machine
medium confidence · Jeff speculates: 'I could have it triggered drum instruments to try to make a drum machine out of this, which is something I think might be kind of neat.'

Hey everybody, it's Jeff from Dirty Pool Pinball. I've got a fun video today inspired by a video that was sent to me with a bunch of birds eating bird food. Now wait, I know before you leave. It was a sound experiment done by Amadeay is a French installation artwork or artist. I'm hoping that I'm pronouncing that correctly. Uh where birds were just eating food out of a bowl and it was triggering sound events.

I was like, we should do this with a pinball machine. Easy. So I did. I got some Piso electric. These are also referred to as contact microphones. And they're spread underneath the inside of the shadow. And I have set up multiple layers of sound layers that are triggered by these events. So the little impulse happens and it tells the computer, hey, trigger this sound and modulate it in c certain ways. So that's all set up and it's neat. I think it's really cool. Hopefully you agree. But you know, how do these work, right? I'll turn it on here.

and press this up against my voice box, you're going to hear a little different. It's reading the vibrations instead of actually moving the diaphragm. And uh that's the principle behind contact microphones and how we are getting that sound from the pinball machine as these are attached to the playfield into the computer.

1:19

So, let's go listen to what that sounds like. So everything you're hearing right now when this happens and I pull this trigger uh is in real time. It's not being done in post. It's being generated live uh as we play. So let's dive in.
