I have MP3 file and the contents are continuous and slow. Is there any tool, which converts them to fast speed.

I am aware of the fact that with VLC, i can play fast. But, the problem is every time i have to fix the speed of the player.

The Question is, i dont want to manipulate/tweak every time i play the file. I wish to have permanent solution to play the slow playing MP3 files to play fast (some thing like saving the file with fast speed etc).

Audacity will allow you to change the timing settings so you can play it at its correct speed. It's free and an excellent audio editing tool.

SoX's speed predicate will allow you to adjust the speed of the audio file. tempo might also be useful.
