I did a firmware upgrade on my MP3 player this morning. One of the features of the update?

The ability to support individual tracks of more than 18 hours duration.

Now, if it had been 18 hours, 12 minutes and 15 seconds, then I'd have understood.

It probably was that long, it's just that round numbers sound better when talking marketing.

I almost certainly was that long. But (a) now I've done the upgrade, and (b) I'd be buggered if I'm going to try to find/synthesize a track between 18 hours and 64K seconds in length in order to check.

Nice.

It probably is 216 seconds, but marketing would call that "more than eighteen hours", and probably thought "almost a day"

I think it must be the size of their seconds counter, and they've rounded it. I thought of other possible candidates likes total number of samples, number of blocks in the mp3 file, and so on which I've seen cause problems in other audio software, and none of them have limits at 18 hours.

Indeed.

It was when I multiplied up 18 hours to see how many seconds it was that I noticed the fact it was almost enough to overflow an unsigned 16-bit counter.

(Hell's teeth, guys, the last time I really noticed a 16-bit rollover was when I discovered the 6553.6 credit wraparound in a single transaction bug in Elite, sometime shortly before that game was released in late 1984.)

I must admit, I do wonder who came up with the track that broke it.

Edit: Whoops, a year out in my original Elite release date.

I remember when Demon triggered a bug in the BSD kernel caused by having more than 64K routes going out of the same network itnterface.

Tried to think of anything that I'd want to record for more than 18 hours, and figure it could be used for recording bird song etc. and just leave it on for 24 hours recording ...

... or an all day/all night filking session ...

... though I'd have had the recorder break things at silences if possible ...

... ditto for a phone monitoring application for call centres ... I'd break it by conversation.

I can't think of a single recording of more than, say, 5 hours that wouldn't be better broken into tracks.
