$750-1500 CAD

Paid on delivery
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. [login to view URL] 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.
