No wonder the audio sounded like a loop. I was wondering about what kind of encoding was being used, for this sound to be generated. Initially I thought it was related to the mp3 file I was "sending" (my computer has no mic), that it may have a pattern in it, but after attempting to send a pdf, the pattern was still there. Feels like a ripoff, since if it uses the internet, it can't be used offline as the title suggests.
