Do you think that it would be useful to have an in-browser audio decoding of signals, i.e. support for various digital mode, as fldigi [https://en.wikipedia.org/wiki/Fldigi] does?
Tune in to a station, and see the morse output right in the browser..?
What I'm not sure of is if the signal will always be good enough to decode it. In fact, I suspect it won't always be good enough to decode it automatically.
Obviously, we shouldn't let perfect be the enemy of good and it should just fail gracefully when the signal is degraded too much.
But, it potentially becomes a support nightmare. While we may know that the trouble is the signal degradation, I suspect many people wouldn't and they would try to place blame on the developers. It may make identification of actual software problems more difficult to assess.
Still, I say it would be a 'killer feature.' I have pondered it before but I'm not a very good programmer. I am pretty sure that some of them would happily add it right to their site, should someone make it. There are a lot of great features that could be added along with it - such as outputting it to a chat room that was dynamically created for that specific frequency. It could even be tied into a social function where a group of people might select to all move to a different frequency together and it, the decoding software, would follow them along. Perhaps the channel could monitor multiple less-active frequencies. That sort of stuff.
I think it would be a wonderful idea and think that good is just fine, and that I'd not expect perfection.
That said, I'm glad I'm not the only one that finds the place to be a time sink. I've spent more hours there than I care to admit. I favor the site that I linked directly, but that is mostly because that is the one I discovered first.
Depending on where you live, you can possibly also find local feeds from people's scanners. You can listen to the emergency responders, police, and things like that. It's not quite the same, but it is similar enough to where I figure I'll mention it. I don't usually bother with it, because I have a nice scanner already set up. Still, it is pretty fun. Also, if there is some sort of major event, you can go listen and hear what is going on before it is covered on the news. That's always fun.
Though there is also OpenWebRX at http://sdr.hu/openwebrx, which does essentially the same thing but is more open source. It has some decoder plugins already.
