To create an app that monitors audio for tone pulses of approximately 2 to 8ms in duration and store the start time in a queue. The app would have a separate thread to process this queue looking for 4 pulses within a 300ms period, measuring the three intervals between and using them to look up a corresponding ID number.
The user interface will be simple with a few setup parameters and a simple display of the code number each time a valid signal is detected.
Technical skills are required. The Freelancer must have some experience with signal analysis and understand the concept of A/D sampling and calculating average power of that signal in small blocks of time. If you understand the concepts on this page, you should have the background needed.
