Simplest thing in the world -- stop worrying about converting or stripping the DRM....just install faad and be done with it.

A friend I just switched over to Debian has about 1000 tunes locked up with Apple's DRM (AAC) format.  All her files are m4a and I don't know if this works for the other types, wmv, mp4, those files.  I think that I had no trouble at all playing them on my Debian box in the past -- but I never bought tunes at iTunes and they were friend's files or something.  The point is, they played.

I have installed on my box for multimedia:

ffmpeg (the one ring to rule them all)
w32codecs (oooh, non-free!)
faad
vlc
lame
audacious
mplayer
whatever Gstreamer dependencies went on with what i've got.

I think itunes is at version 7.x and I know hymn stopped working at version 5.  There are a zillion appys out there that purport to "unlock" your DRM'd tunes on the Windows platform, but -- we're used to that kind of crap there.....everybody and their brother makes claims about their shitty shareware for the WIndows platform.

Anyway -- any of you get burned by itunes?  Bought a shite-load or DRM'd tunes and you're stuck?  Oh, I know that if you point VLC to your "key" (in your user profile on your Windows box) you can authorize those tunes (in a manner of speaking) -- but why go through all that?  Faad.  Do it now.


I suppose if you really wanted to convert one lossy format into another one (why, it's gonna sound like ass) the you can do this:

faad -o - pensive_pop_tune.m4a | lame - Worse_sounding_pensive_pop_tune.mp3

Report back about m4p and any other Apple file types.

Rockin' -- I'm groovin' to shitty pop music.  Some people just have no taste at all.  I need to introduce my friends to Frank Zappa or something instead of all that pensive and whiney shit they listen to.  Pffft.

Lol -- I figured everybody already knew about it and I am about 2 years late to the party.  Maybe I shoulda posted this a long time ago.

Oh, just as an aside -- when my sister-in-law (the mighty evil one) gave my wife her ipod it was full of m4a tunes.  Well, I remember that I liked about 50 of the tunes that she had, so I copied them to my drive, fired up a terminal and ran dir2ogg on the lot of them.  In no time I had a pile of ogg files.  But the thing is, you'd be going from one lossy codec to another one.  Anyway, it works fine.

As well, you ain't playing no .ogg tunes on your ipod unless you install rockbox or something like that.  Pffft....my ipod rocks the oggs!
