Why doesn't changing the pitch of a track change the time?

Quite a weird question, but I've recently wondered why pitching a track up by, lets say, 4bpm doesn't make the track run a bit shorter seeing as it's technically four BPM faster. I know that pitching a track just modulates its pitch and not its speed, but if pitching a track up can add a few BPM, shouldn't it also technically last for a bit less? Or are the speed changes according to pitch all perceived and have no effect temporally?

it does, check the timer on your cdj, it runs slower if you pitch it down and faster if you pitch it up


Easy to spot if you have it on wide

It does change the actual time however on some players the displayed time is in "0% seconds" rather than literal seconds

So the numbers won't change, they'll just tick by faster.

Ahhh, thanks, I've just been trying it out on Traktor. No change there, can't remember if there is on CDJ100s although there probably is?

Traktor will not show a change in the analyzed master length of the track but the actual time the track plays does change by a few seconds up or down.
