What are the best available software and programs for music editing?

I am a big music lover and I always edit the format of music.So that I can use it in mobile or iphone or other devices. For that I have to use some software through which I can convert audio or video into any format like WMV and AVI or MP4 or edit it in any format. For that I normally use AVS software or free blue audio to video converter or editing of the music. You can also change the format of your music in any of them or edit your music by simply downloading those software from the internet or you can just use them online. After that you can download those video or audio to your iphone or computer very easily. So, I am giving you the name of some websites from where you can download converter and editor software or you can convert your media format directly.

Media converter, formatoz, any video converter,cocoonsoftware, cnet, brothersoft, makeuseof, these are some websites from where you can easily download those free media converter and editor software. You can easily use those in your computer or mobile or in any other devices. It was really fun to help you.
