Accuracy of track duration display

[Loweaul]

    A few of users in other forums mentioned that some of the music durations isn't equal to other Music Players,

 

    From top to bottom you could see the timecode in Foobar2000, Xiaomi Music and PA. and then I try to measure the duration more accurately.

    and the music duration is 3:23.894, I've tried to compare the music one by one, and I guess maybe the measurements between those music players are quite different?  Anyway I'm uploading the file see if you can do something or not, thanks a lot.

What happens on the affected file when you view info/tags in Poweramp during playback?

 

I'd wager PA knows the accurate durations, it's just rounding up instead of truncating it like other players.

@Loweaul I checked in Audacity, and the exact length of the audio content when expanded seems to be 3m 23.894s. Some programs show that truncated as 3:23 (e.g. VLC, TagScanner, ZoomPlayer, Windows Media Player), some show it more accurately rounded up as 3:24 (e.g. foobar2000, MP3Tag, Poweramp). Windows 11's Media Player gives 3:22.

The header data shows total samples as 8,991,735, which at 44.1kHz I guess would give 3m 21.627s, so maybe there's some padding included too?

Personally, I would say 3:24 seems the closest to correct - but without multiple decimal places, take your pick basically. Not really worth worrying too much about one way or the other though, the last second or two of the file is silence rather than song anyway.

@Fitzian Yeah I guess PA is more accurate

@andrewilley I see, thanks for the explanation!
