RadioReference.com, touted as the world’s largest radio communications data provider, also offers the largest broadcast of public safety live (real time) audio communication feeds. If you are a public safety scanner buff you can get thousands of live audio broadcasts of Police, Fire, EMS and other associated feeds, on your computer (and mobile smartphone) from various points from around the world.
Simply visit the site [HERE] , find your location of interest, and a list of live feeds will be generated that you can select from. Once you find a feed, you will see a “speaker icon” adjacent to the feed. Click on that icon and you will have various options to connect to the feed (such as web player, windows media player, etc…). I found that the default “web player” worked best (easiest) for me. I think you will be surprised at the list of feeds that are available; AND, that this list is growing daily.
