That looks awesome! Like megrimm said, I like the physical visualization of the code with the water and air pulses.
Apologies in advance for going more tangential, but I've been intrigued by the interplay and interconnections between telecommunications technologies and art, although my technical knowledge of the former is a bit thin... And esp as a percussionist, I could see morse code transcription as a basis for an interesting audio/visual performative piece. I've def got to look into it more, the most I've done with morse is do fake morse code by playing random sequences of beeps on a bunch of networked phones...
This e-mail thread has been inspiring, thanks pd-list! Back to regular pd-list programming...

It is a little bit [OT], but here is an installation I co-produced with Cécile Babiole. It is a chat between two people based on a network working with water (coding en decoding (extended) Morse) : http://babiole.net/spip.php?article101 It is now exhibited in Espace Gantner in Bourogne (East in France) : http://www.espacemultimediagantner.cg90.net/exposition/anarchronisme-machine... ++

Is [list-compare] from an external library? It's not in vanilla.
I forgot to put this in a subpatch, sorry for that, it's in [list-abs]

Hello,
I've made such patch to decode termites hammering into morse.
It uses the process described by andy, and datastructure for storing characters, it could also now be done with [text]
I've made a version where [env] testes if there is sound amplitude or not,
and compare with templates stored into datastructure.
Attached is that version that should work with mjlib/morse and latest pd-vanilla.
Best,
patco

Yes did that once, but I lost it years ago (the patch I mean)
IIRC its not that hard.
Use a [timer] and onset/tone detector, and an array that looks up the next state. You need a way to navigate a tree - a state machine with 26 terminal nodes (36 if you want numbers) and there are four symbols to transition states, dot, dah, short space and long gap (between letters)
The array is a 4-tree collapsed into a "Turing tape" so you use the symbol to select the offset (jump) to the next state (table index) based on the last symbol. A long gap always resets the index to 0.
cheers, andy
