MP3 Files into WAV files

[scrubed]

Hi,

I want to edit an MP3 file. The only way I can think of is convert to WAV, then open with Sound Recorder and start chopping at each end until I'm left with the bit I want (which is in the middle).

1. Can anyone tell me how to either convert an MP3 into a WAV, or

2. How to edit an MP3 track?

Thanks in advance.............
