@kRazzyR: for f in ls; do ffmpeg -i $f $(basename $f).wav; done – datakid Mar 31 '18 at 02:06

@datakid Looks like syntax highlighter ate several symbols in your code. I've added your working solution into answer as UPD. – NG_ May 02 '19 at 11:39

@datakid You should not parse ls output. Instead use for f in *.mp3; do ffmpeg -i "$f" "$(basename $f).wav"; done. This also includes proper quoting and limits calling ffmpeg for mp3 files only. – scai Feb 17 '20 at 20:32
How to get 32 bit floating point wav with mpg123? – F. Vosnim Jun 26 '20 at 12:54
You can get 32 bit float wav output by adding the flag: "--encoding f32" or "-e f32" – Ethan Apr 13 '22 at 18:58

soundconverter is also able to do it

sudo apt install soundconverter
soundconverter -b input.mp3 -f wav -o output

Will create a directory output and convert input.wav into it.
