iPod BPM?

[ChazLM]

No...not BPM on XM! Is there a program out there that can measure the beats per min. of a song, and then allow me to manually speed it up or slow it down? I know itunes has a column for this, but most songs don't have a number there. I'm trying to make an exercise tape and want to control the tempo of the workout. Thanks for any input...

I think most BPM counters require you to tap a key at every beat, and the program will count them. A counter like this is available as iTunes plug-in: http://www.blacktree.com/apps/iTunes-BPM/ I have been using it, and it's fairly convenient if you accept the tapping part. I am not sure if there are any BPM programs on a Mac that do not require human interaction.

As far as changing the beat, I am not sure it is possible for files that are not MIDI or similar format. Increasing or decreasing the BPM of an MP3 or AAC file will probably change the pitch as well.

WiMP 10 does it pretty well you can speed it up or slow it down ie 2x, .5x, etc
