A Processing project that converts sound files to vector PDF.
If you want to export your sound to vector PDF, please put sound.mp3 file into the folder containing the app/sketch. Then launch the app/sketch and wait until the app finishes playing and exporting. The file which it exports should be called sound.pdf and it is in the same folder as the app and sound.mp3. The waiting part with the music playing is a feature, it is like copying cassettes. Old school? Don't you think?
P.S. Again, this is only a draft so don't expect something big.
