[PD] Morse Code Translator / Decoder

[patrice colet]

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
