Cant say ive had a problem with iTunes V7 here (on a mac, maybe its bad on PC's?).

Anyway, Im sure QuickTime can convert files too. So theres another option.
However, I wouldn't do it. You'd be converting 1 lossy file format into another lossy file format, and you WILL lose sound quality in the process (not everyone would notice it, but I know I certainly would notice).
If you want to do it because your MP3 player doesnt like M4A files, then you might consider converting the file into a non lossy format instead, like WAV or something like that, which the mp3 player probably will play. The file size will be larger of course, but you shouldn't lose quality this way at least.

Cheers, P

I bet you that you couldn't tell the difference between two files converted from M4A to MP3 at 192kbps.....Unless you are playing on a pair of Sure E5c earphones in a totally quiet, acoustic room, it would be utterly impossible!!! Especially on a bog standard MP3 player.

Stick with your MP3's and forget the WAV option. If you have a 256MB player, you can only fit half a CD on there and 1GB will allow you about 1½ CD's. Not exactly what a portable player is all about.

There's being an audiophile and there's being practical. For this problem, I would suggest being practical.....

I get (and I'm not the only person if you look in the Apple forums):

- scratching and hissing music (Apple acknowledge this as a QT fault)
- poor video performance (Apple also acknowledge this as another QT fault)
- 25% CPU usage just playing music! yikes
- 100% CPU usage just browsing and playing a movie

The new design is great and I love the album flipper thingy. But they really should have done a little more testing before the release!!!!! rolleyes

Again, I can tell the difference.. Taking a compressed audio file thats had bits thrown away (lossy), uncompressing it, then compressing it again with another lossy codec will show up problems.
I can tell if its been compressed once, and certainly can if its been compressed twice. Even more so if you are going from a more advanced codec such as M4A (AAC) to a dated MP3 codec.
As I say though, some people wont notice the difference anyway, so it wont matter one iota to them. In which case go right ahead. However I definitely do notice the difference. But then i've done plenty of sound engineering as a job before, and still have a pretty good sound system here at home so maybe that makes me more likely to notice the difference. But im not anti digital music either.
Also, listening to music on Shure E5C headphones (sealed in ear canal jobs if I remember rightly), in an acoustically treated room? Pointless. Speakers in an acoustically treated room however, thats another matter entirely.

And as a sound engineer you should know any outside noise will interfere with any type of in-ear canal earphones. It's common sense to be honest. The E5c's are sealed, but not totally.

Sound travels through the body as well as the ear and this will change the sounds characteristics. Anyhow....nuff said on this topic I think.

Common sense? Common sense says "When in hole, stop digging"
With all due respect, you have little clue what you are talking about.
