How to detect truncated MP3 files

clean.sh

# Retrieve MP3s list
find . -type f -iname "*.mp3" -print0 | while IFS= read -r -d $'\0' line; do
    # Use sox to extract a MP3 which ends at 0 seconds of the current file
    sox "$line" temp.mp3 reverse trim 0 reverse
    
    # We retrieve original file and copy durations, as integers
    ORIGINALDURATION=`sox --i -D "$line"`
    ORIGINALDURATION=`printf %.0f $ORIGINALDURATION`
    COPYDURATION=`sox --i -D temp.mp3`
    COPYDURATION=`printf %.0f $COPYDURATION`
    
    # A comparison is made between the two values
    DELTA=` expr $ORIGINALDURATION - $COPYDURATION`
    if [ $DELTA -gt 10 ]
    then
        # If the diff is more than 10 seconds, we rename the file
        echo 'ERROR : '.$line
        linenew=`echo "$line" | sed 's/.mp3/.fail/'`
        mv "$line" "$linenew"
        rm temp.mp3
    else
        echo 'OK : '.$line
    fi
done
