Support for recording the *current* track

[navid-zamani]

By always keeping the entire current track in the buffer, recording the current track retroactively can be implemented very easily.

Simply start a new buffer when a new song title is received, and grow it until the next title or until a size/time limit is reached.
So a very long track (10min) could still be “recorded”, 10 minutes in, but a 2 hour DJ session would be a bit much. :)

At CD quality, this would take less than 10 MB of RAM.

From experience with my own scripts back in the day, I know that „keep last track” is useful too, but it needs to come with a “keep second to last track”, as many radio stations will quickly change the title for some in-track ads, and then the ads would be the “last track”.
Due to memory concerns that one could be option though, I guess.
I personally always kept it enabled even back in 2009 due to its high usefulness.

Another very important thing that StreamRipper did back then, was to keep a bit of the last track in the next one and vice versa. Because the title changes often were not very exact. It had a nice algorithm though that looked for the nearest quietest part within a range. That did not work on DJ sets though, so the “keep a bit of overlap” was still necessary. If you don’t already copied StreamRipper, I can only recommend looking at their algorithms, as they are well-polished and well-documented in the help. (No idea if SR still even exists.)

Right now, the fact that one can neither keep nor bookmark the current track is a bit unfortunate, because that is usually the one one is interested in.

(Anyway, the app is very nice. :)
