So I have just tried "smart convert" don't seem to work? I am wanting to convert my mp4 tunes to mp3 anyone have experiance of one that works, Im using an macbook pro
For the small scale stuff that I do, I use Audacity. It's free and relatively easy to use. I'm pretty sure there is a MAC version of this.
I've used DBpoweramp for 3 years on XP running in Parallels on my Mac, but it is now a beta running natively on OS X, Mavericks and above, This beta is working fine for me so may be worth a try? dBpoweramp Music Converter Apple OS X R1 Maccaa
Go iTunes prefs>General - at the bottom is 'Import Settings' - change the 'Import Using' to whatever mp3 setting you want - then select a tune in iTunes and from the 'Advanced' option in the menu bar select 'Create MP3 version'. This will create a .mp3 version and the original .mp4 will still be there. Used this to create a USB stick of music to work in the Wife's Clio MediaNav.
