Alternative - mpg123

Hi ,if possible could you expand it to run on all files in a folder?

[datakid]

@kRazzyR: for f in ls; do ffmpeg -i $f $(basename $f).wav; done

@datakid Looks like syntax highlighter ate several symbols in your code. I've added your working solution into answer as UPD.

@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.

You can get 32 bit float wav output by adding the flag: "--encoding f32" or "-e f32"
