I found Gold wave as the best Audio editor, very easy to use, you no need to watch any tutorial for using this software and you can edit audio like PRO. with the use of fabulous features like fade-in, fade-out and Cross-fade you can join two or more audio easily and smooth. Volume control is the best part of this software. You can export audio in MP3 easily. Review collected by and hosted on G2.com.

Honestly, there is nothing which I don't like about this software because it is the best among other software available. but it can be a cherry on the cake if they provide a better GUI. Review collected by and hosted on G2.com.
