Hello,
Has anyone made a patch/abstraction to "decode" or translate morse code to text? I see text->morse but not the other way around....
thanks! m

Not AFAIK, but the problem would be, how would the input morse code be encoded? Audio Beeps? Audio "Ticks"? Light? text? binary digits? What timing convention? (see e.g. [1]). Seems like just the 'decoding' of the message in itself might be an interesting task :)

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

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,

I think a good way to optimize this patch would be also to store strings in [text] object instead of characters stored into scalars, then snd2morse~ would output strings

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...

I suppose I haven't fully investigated the details of morse code quite yet (btw, I've come up with my own pd transcription patch that I can share that uses the [text] objects that Patrice mentioned, but before it comes to that it needs a lot of tweaking...).
I suppose I've been fascinated with how the worlds of communcations technology and music are so intertwined. Stretching the idea of technology a bit, rudimental drumming, something every percussionist learns going through school, has its roots in military (at least back to civil war days, if not earlier) and communicating orders to troops (and I suppose in a superficial way it's related to morse code in how it uses more-or-less codified rhythms to communicate information). The first public wireless radio broadcasts (AM I think) were done by Lee de Forest at the beginning of the 20th C and it was of live Metropolitan Opera concerts. Of course AM (and FM) would later find roles in synthesis techniques for computer music. Jumping way ahead, the Internet has drastically changed the way music is accessed and shared and how it proliferates (not to mention who is able to participate in music creation and sharing). And the technologies that have sprung up around it have opened up new avenues of muscial expression. I've helped out in concerts where live performers play alongside other live performers from the other side of the country (of course not possible without Internet technology). Open-source music proejcts and the communities around them such as this community and Pure Data thrive because the Internet allow the software to be easily distributed and allow the community to organize and contribute. And web standards such as Web Audio API and backend tech such as Node.js have allowed for new ways of interacting with music, I've used them myself in concerts to trigger sounds on people's phones. And of course the big field of DSP covers everything from the the techniques we use in computer music to how cell phones work.
Anyways, I'm not too familiar with the design of the Morse code but I'll be sure to at least read down the relevant bits of the Wikipedia page and/or any other resources you might suggest =).
