reliable bpm counter for Mac

[visine]

Does anyone know of any software for Mac that will automatically tell BPM of tracks?

I've seen quite a few programs but they require you to tap the beat as the track plays but that kind

of manual process is not practical and takes too much time if I was to do it for a lot of tracks.

Oh by the way if the software can tell the tracks key it would be even better but not absolutely necessary.

 

Thanks a lot in advance

You can do that in Native Instruments Traktor DJ Studio
