Kilburn, London, UK
This is an ongoing stream from a back garden in Kilburn, London, UK.
This is a stream running on a Raspberry Pi 4GB that has been running almost continuously since 2016.
Overall, the stream has had less than a week of downtime in that period.
Using two cheap Behringer XM8500 dynamic microphones in an X/Y configuration on a stereo-bar, you'll hear the sounds of suburbian London.
Little traffic, but plenty of trains and seagulls oddly.
Every quarter-hour, the sound of a chiming clock is injected into the stream digitally, to keep track of the passing hours.
