By the way what's better, mp3 or MPEG-2 Layer 3 format files?
Mikey, dont let your head explode.
I'm not sure of the difference, in fact i'm not sure they aren't the same thing; there's MPEG 1,2,2.5,3, and 4. And different layers.
What is different in each is the balance between sampling frequencies and bit rates. And different ones were used for different media, some were designed for use with HDTV, some with Music Audio, some with Broadcast audio.
I think.
The ones used in Video also encode that, at 30 frames [29.97 really, but Mikeyboys head...] a second.
[aside; Video is 30 fps. But Film was/is shot at 24 frames per second. So when they transfer film to VHS [and I think DVD], they have two frames of film, and then a third is inserted, the same as frame 2. Frame 1,2,3,3,4,5,6,6,7,8,9,9... I'm pretty sure is what you see on VHS, hence when you slow scroll through your porn, you see every third frame is the same. fuck that was long.]
A 64kHz/sec bit rate is just fine for talk radio, but 128 is the minimum, usually for iPod Music.
But there is a difference reef, because the sampling rate differs, how I dont know how, coz 44.1 and 48kHz are standards. Mikeyboy, that means a CD/MP3 player takes a snapshot of the sound 44,100 times a second, and encodes it in ones and zeroes.

You hear that? Now THATS Rock!
[OH: MP3, stands for MPEG, which is the Motion Pictures Expert Group. Nice fucking way to name yourselves! Coz JEPG is smething like Joint Pictures Expert Group. Buncha snobs!
And Wav just means un-compressed audio.
Good = Sounds just like your CD
No Good = It eats memory at over 1MB a second.
BUT
With a 600000 Gig iPod out in 2008 or whenever, people can digitize their entire audio and video collections, uncompressed, so we'll look back at MP3 like 8tracks and 78s and edison cylinders....]
