Continuous Audio Life Logs
and the Personal Audio Project

For under a hundred dollars you can buy a recording MP3 player, weighing ounces, that has the memory and battery life to record everything you hear throughout a 12 hour day. Upload these recordings to your computer every night and you have a complete personal audio life log. It's cheap and easy to collect this data, but it's almost impossible to use the recordings for anything without the development of new tools. This project is concerned with investigating the implications of ubiquitous personal audio recorders, and developing tools to exploit this kind of data.
