This means that you have to learn how to use Ruby. You should dedicate
some time to a good tutorial. You will certainly learn how to execute
external programs from a Ruby script.

If you post your attempts, and the eventual error messages, chances
are you will receive useful suggestions/corrections.

Thanks Carlo

But I know how to execute a mp3 file using ruby script and I am able to
set the loudness too using this script
path = “/home/cis/Desktop/ *mp3”
system("mp3gain -c -p -r -d 4.0 "+path)

but what I want is the loudness should be same for all .mp3 files and
that is not coming. I want the loudness to be 93dB.If Anyone can do that
please help me with this.

This has practically nothing to do with Ruby. You should knock at some
audio specialist forum. I used Sox to obtain something of that sort
(roughly having all my Ogg files with a similar loudness), but 93db?
No idea.

Thanks Carlo. BTW I found the solution and have successfully
implemented it.

Would you mind sharing the main gist of your solution for future hopeful
searchers?
