bitrates

[Conor456]

hi just reading some1 mentioning about atrac and atrac+, i was told a while ago that atrac+ at 64kps is the same as mp3 at 128, is this true? also why do people like apple advertise that their ipod can hold X amount of songs at near "cd quality" which usually means 128kps when a cd is 1411 kps (i think) ? im no mathematican but surley theres a big difference between a song encoded at 1411 than one at 128.....

hahahahahhahaha

128kBit is never CD quality, and 64kBit never 128kBit!

Which guy has said this.

hehe, excuse my post

mmh, have a look at these links

As far as I personally experienced and heard, ATRAC and ATRACPlus are better than MP3 in just compression! That means if u have the same song with the same bitrate, both in MP3 and ATRAC, the ATRAC filesize is smaller than MP3

Atrac3 and MP3 are good Codecs. But if you use Bitrates with more as 160 kBit. It's better you use Lame, OggVorbis or my favourite MPC. If you want play your files only on the Computer and you have enough GigaByte, it's better you use a lossless Codec.

lol while we're on the subject of lossless codecs would you mind tellin me what that means? ie what does it have to offer over mp3 etc.. (thanks boss)
i'm not one for namin names but the guy replyed to a post i made a while ago thats now around page 11(or more by the time you read this), its the last post (theres 2 pages)

Conor,

it's a real strange topic. Look here .

Or have a look at this site.:smileywink:

Frankly I don't have much technical information, but lossless means that if you rip a CD and convert it to a lossless file, for example OGG Vorbis, you get the CD quality music with your digital file! You'll need a lot of Gygabites, because perfect quality doesn't come cheap, but it worth it if you have a huge HDD!
But codecs like MP3 or ATAC, are lossy, that means they compress your music to very small filesizes, but you'll lose lotsa quality respectively to your codecs bitrate!
Bitrate is the most important thing! and the higher the bitrate, the higher the quality!
(sorry I'm repeating : lossless codecs don't touch the original musics' bitrate!)
VIVA LOSSLESS

Bitrate is the most important thing! and the higher the bitrate, the higher the quality! 

MPC is on of the best Codecs, if you want a bitrate between 160 and 180kBit. Lossy Codecs with a bitrate of 200 and more aren't really usefull, because the quality isn't better. But the file is bigger.

lossless codecs don't touch the original musics' bitrate!

If you means lifemusic, I agree.

I personally use different bitrates for different source music.

132kbps Atrac3 for ripping CDs and 256kbps Atrac3+ for recorded vinyl.

The listening tests Sony have done on the Atrac family against MP3's of similar bitrates have always proven that Atrac has come up as sounding better, Atrac3+ is very good and sounds much less mushy than an MP3 encoded at a similar rate.
