Is a good thing, talk about the soft we use because we don't experiment whit the lot of stuff are everywhere. only write the name of 3 prog's, if everyone give 3, we have a great list of software to use.
My Favorite's are...
Adobe Audition, Is a powerfull program to edit, restore and create audio files, is easy to use and... Have the posibility to create or use files in a 128 channels console.
Jasc. Paint Shop Pro, more than photo paint or others programs for image edit, this program is so easy to use and have some funtions are taken by others programs/companies, after it apears in this program and they see are great.
TuneUp Utilities, Have a great tipe of PC utilities and it work in win XP or Vista.
customize your Win, check all the comp, memory, HD, etc. Is simple and powerfull.
That is the 3 programs I recomend, write the 3 you like more.
