A question-can mp3's and AAC files coexist on the same iPod?

Yes. I reripped 3 or 4 albums in AAC and the rest of my library (around 1000 songs) is still MP3.
# 2 Re: AAC & mp3
Can someone simply explain what the advantages are to having your music on your iPod in AAC format instead of MP3? Also what ripper do you use for AAC (I use CDex, but is for MP3 not AAC). What program to convert existing MP3 to AAC? Thanks.
# 3 Re: AAC & mp3
it's my understanding that a windows formatted ipod does not have aac support, right?

mongoos150: aac has better quality at a lower rate, so you can:
-have smaller files by ripping at a lower rate and save space without having to give up quality
-have really high quality files if file size is not an issue
there are a bunch of other differences, but i think the quality one is the biggest
Bakerman: the new ipods have the ability to store them. the older ones do not, but will most likley get it later this year when the itunes music store is release for window

check out this aac vs. mp3 (http://www.recordstorereview.com/misc/aacmp3.shtml) test and this aac vs. mp3 vs. ogg vorbis (http://www.phataudio.org/modules.php?name=News&file=article&sid=134&mode=thread&order=1&thold=0) test for more info.

# 6 Re: AAC & mp3
There are a few encoders I have heard of that you could use with CDex that encode in AAC(psytel, FAAC, etc.), but from what I've read at www.hydrogenaudio.org (http://www.hydrogenaudio.org) , there isn't really a good one that will work with the new ipods. There are several types of AAC, including types with extensions like .aac, .mp4, .mp2, .mp4a, .mp4p. I think that someone on that board came up with one that works, but so far Windows Ipods aren't supposed to be able to use this. However, Ephpod might be able to move them soon, and there's a program called db poweramp(http://www.dbpoweramp.com) that has a plugin called Sveta portable audio. The guy that runs it is a member of hydrogenaudio and said that it can already transfer AAC, but without tags. He says there will be a working version next week, though.
I can't be sure of all of this, though, because, the peopleat hydrogenaudio know a LOT, and I can't understand everything they say. Keep an eye for developments at the DB poweramp site, though, and I'll try to post a new topic if I find a definitive answer.

Sveta Explorer from Spoon (dbpoweramp) can upload .mp4 (aac) to the iPod right now. It has a few bugs, but nothing significant. Just convert with DMC (dbpoweramp music converter) and upload with Sveta Explorer.
Nero, the burning software, can convert to .mp4 that will play on the iPod as well.
The thing I don't like about .mp4 is how slow the encoding is compared to LAME .mp3. It's almost unbearable.

At this time, you can only use AAC on a Macintosh-formatted iPod using Mac OS 9 or 10.
Therefore, I wouldn't worry too much about how to create AAC files on your Windows machine; your iPod can't use 'em.

AAC works fine with firmware 1.3 and 2.0. For the PC ipod, there's a firmware 1.3 updater hack from http://www.the-midfield.com/ipod.aspx . I've used it and it works.
Ephpod added rough AAC/mp4 support last night. You have to change the extension of the mp4 to m4a or m4p in order for Ephpod to transfer them to the ipod. The only two problems right now with Ephpod and AAC is that track length is read incorrectly and tagging files is a problem (hopefully they'll be fixed in a few days).
I'm currently ripping all my CD's to wav. And I'm going to use Nero to encode them to mp4's. I'll transfer them to my ipod using Ephpod as soon as the above problems are fixed.

I run WinXP Pro and have a new 30GB iPod. Works fine for me. Converted with DMC, transferred with Sveta Explorer and played the mp4/aac file with zero problems. Playlists are another story though as Sveta doesn't handle them properly yet.

You can label mp4's with winamp once you get the AAC plugin.

Spoon expects the major bugs for the sveta drivers to be worked out in the next week.
# 13 Re: AAC & mp3
I have all of my songs in 320 mp3, and I encoded some in 192 AAC (at least I think it was 192) with dbpoweramp and was slightly dissapointed, but I think that is from listening to 320 mp3 for so long. I am going to try 256 AAC later, but it takes so long to encode (320 mp3 is a full cd in a matter of minutes, 192 AAC was 2 hours for the same cd, maybe even longer).
I used sveta and it worked fine. You can upload the file with sveta and then tag it while its on the pod with EphPod.

The bonus for me was file size, it doubled my iPod size due to AAC files being smaller. I did many tests of my own cd's, ripping them with iTunes from 64 -192 both AAC and mp3. The 64 AAC file sounded the same through my stereo, car stereo and ipod headphones. If I want to hear better quality, I put the cd in the stereo! But honestly, I could not hear the difference b/w bitrates... I'm probably losing my hearing!

:eek: 2 hours to encode? I'm not going to be using AAC at all if it takes that long... what speed of machine do you have?

# 16 Re: AAC & mp3
I'm a Mac user and I use iTunes4 to rip and encode my music to ACC. It does take longer than mp3 encoding but not 2 hours per album. Mind you, I'm encoding at 160 ACC and 128 ACC not 198, 256 or 320.
# 17 Re: AAC & mp3
Same goes for me - iTunes encodes AACs at about 5-7x speed.
