while i find the idea intriguing, i think it needs a lot of refinement. Â the idea of auto-surveillance came up as i was working 8 - 10 hour days doing landscaping for my parents' house in pennsylvania. Â the original idea, which i still would like to pursue, was to analyze the incoming signal with a filter bank to classify events by their timbre and amplitude. Â this way, i could build a database of short environmental samples for later use. Â as i have had very little time to write any code, this experiment proved quick to implement and yields some satisfying results. Â since i'm about to push off for a long road trip across the country, it feels a bit like how sailors would take handfuls of dirt and put them into jars. Â i am looking forward to collecting more specimens as we travel.
