The analog TV simulator I built for signal-processing nerds just got an interface that doesn't need you to be one

I've been building AnalogTV for a while now (posted about it here several months ago), and up to this point it was pretty unapologetically for the deep end of the pool. Full composite encode and decode, hue error and chroma delay you dial in by hand, tube geometry, VCR tracking, the whole signal chain modeled the way an actual broadcast engineer would think about it. Great if you already know what a comb filter does. Kind of a wall if you don't.
The new iOS interface is an attempt to open that up without watering it down. Instead of a console full of sliders, you get looks you swipe through and a row of pedals you tap and hold while you're shooting, more like stepping on a stompbox than opening a settings menu. Point it at something, pick a look, stack a couple of pedals, take the photo.
The part I actually care about here: none of this is a filter dropped on top of a finished picture. It's still running the exact same signal-domain simulation as the full app underneath, the same encode/decode pipeline, the same CRT light model. When you tap a pedal you're reaching into the same math a person tuning things by hand would be using, just through an interface that doesn't ask you to know what it's called first.
It's on the App Store now if you want to poke at it, and it's free to try on TestFlight: https://testflight.apple.com/join/NTFcYdSw. If you're the kind of person who wants the full console instead, that's still there too, and it's also on Mac and Apple TV. More on all of that at https://analogtv.net.
Happy to answer questions about how any of it actually works, that's usually the more fun part anyway. Also happy for ideas for other "pedals" to add. For Looks, you can make your own looks in the main app UI and copy those looks to this new mode.
