You can decode de mp2 (mp2=mpeg layer 2) with an audio player, like winamp, foobar (free).

In foobar2000 v0.83 you can use:
1. setup to output a mono wav.
Menu: Foobar2000 > Preferences > Components > Diskwriter > Processing > Use DSP
Menu: Foobar2000 > Preferences > Playback > DSP Manager > "Downmix channels to mono"

2. convert mp2.
Drag & Drop file 2 foobar, right-click > Convert > Run conversion

boilá!

Note: I don't know about the CLI way. The following can help:

"lame.exe fixed for .mp2 decoding: includes lame.exe only (ICL4.5)

Lame is excellent quality command-line (maybe CLI) mp3 encoder that can decode mp2!

maybe Besweet can convert WAV stereo 2 mono.

Many audio software can do this, like:
Cool Edit Pro, Soundforge, many more :P

You can use MADplay to do this:

madplay -m -o output.wav input.mp2
