I could not find a working example for command line VLC to convert a WEBM video file to an MP3 audio file, so here you go:
vlc -I dummy INPUT_FILE.webm --no-sout-video --sout-transcode-samplerate 44100 --sout "#transcode{acodec=mp3,ab=128,channels=2}:std{access=file,mux=raw,dst=OUTPUT_FILE.mp3}" vlc://quit
