live atc isn't exactly live either, at least the BOS feeder is off by probably 30-45 seconds. Obviously due to the time it takes to feed and then come through my computer.
Not that it matters, just something i noticed.
True, but as far as receiving live ATC frequencies over the air using a scanner, converting the signal to a digital stream, uploading this stream to a server, downloading it across the vast chasm that is the Internet to an audio player that decodes the stream into analog audio that comes out your speakers, it is as close to live as current technology can deliver. Ha...
Or, in other words, there is no intentional delay added to the feeds.
