You can use lame to decode mp3 file to wav file, usage:
lame.exe --decode --mp3input "input.mp3" "output.wav"

Is there a way to resample the frequency of the output file to 48Khz?
The --resample option doesn't work with --decode.

Thanks for your answer

You can use SSRC (http://shibatch.sourceforge.net/) to resample decoded wav file.
Sample command-line (it's not perfect but resampling is very high quality):

lame.exe --decode --mp3input "input.mp3" "tmp_output.wav"
ssrc.exe --rate 48000 --twopass "tmp_output.wav" "output.wav"
del "tmp_output.wav"


or you can use my simple batch script:

http://www.sendspace.com/file/eb1jww (dec_res.zip, 272 KB)

Package includes LAME v3.97, SSRC v1.30 and dec_res.bat batch script.

Usage sample for my script: dec_res.bat "input.mp3" "output.wav" 48000
where 48000 is output file sampling rate.
