Anyone use any free sound mixers or editing programs they really like? I use Audacity and it works really well. Any suggestions?
If you want to create your own Music and know even something about Piano(or any other keynotes) you can use Anvil Studio . Its 4 MB download
and full fledged Music Studio . Perfect partner for Audacity !
As far as multitracking, mixing and mastering goes, Ardour can’t be beat when it comes to free apps. You need a better than average soundcard to take full advantage of it though.
mixing in my sound i use fl studio 
Thank for the replies. I already have Anvil Studios and it work great. Looking forward to checking out the other programs!
