Automated MP3 conversion?

I have a scenario where I’m delivered a file every hour for a radio station. The file is MP3 at 64k 48000. The system it plays in requires at least MP3 128k 44100. I’m looking for a solution that can be ran from a command line. The FTP Client I use has an ability to launch command line or files after the file downloads.

LAME may be used from the command line.
If you don’t already have LAME, you can get it (free) from here:
