You will find that ALOT of audio editing programs say free trial and what not ..but then after you spend the time editing your sound ..they wont let you save ..or limit the length of the music ..which is very annoying. Then best free trial/program i have found is audio edit deluxe http://audioedit.mystikmedia.com/


it has a free trial that is full version for 30 days ..with no limits during those 30 days and it is very easy to learn and is very good for all types of editing and converting
