This project involves building a "Bird Translator" that will listen to bird song and translate to English (or other human language) using the Solresol musical language invented by Francois Sudre from 1827 onward. This is coded using the "Pure Data" graphical language. The bird song is analysed and converted to musical notes in groups of four and then the words looked-up in a Solresol dictionary. The words are shown together with optional colours and music. Various different outputs and configurations are possible, outputs can be saved for further processing. The system can operate with either recorded or live sound. There are three versions; full, lite and pi which can all run on PC or a Raspberry Pi.
