Continuous Real Time Pulse Code Decoder

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.

If you have the technical background and experience with Android, this project should be fairly easy.

Please mention your signal processing experience in your proposal.
