AAC encoding slower than MP3
re-encoding my stuff in AAC I've found that it's maximum speed is 7.5x on my iMac (800/15"/512) no matter wether I use 128, 160 or 192kbps. This compared to a speed of between 9.5 and 12x when encoding MP3s.
7.5x seems pretty lame and it must be much worse on a G3 system. What's everyone else found. Any chance of it improving?

I would kill for 5x-6x RIPP speed. so quit complaining.

I love polite reasoned replies
Thank god I can't ripp on the Beige G3 due to a glitch which gives cracly audio so I have to use my mom's iMac when I go to her place (the 2.5x is an est ripp speed for AAC)
Track is "Don't know why" - Norah Jones (just a cd I had on my desk)
Encoder - Bit Rate - Speed (top) - File Size
AAC - 128 - 5.8x - 3.0mb
MP3 - 128 - 4.0x - 2.8mb
AAC - 160 - 5.4x - 3.6mb
MP3 - 160 - 4.5x - 3.5mb
AAC - 192 - 5.3x - 4.3mb
MP3 - 192 - 4.9x - 4.2mb
At least on my test, AAC encoding is considerably faster than MP3 at any given bit rate. Files sizes are similar, but sound is much crisper and fuller under AAC. IMHO and using headphones, AAC 128 sounds much better than MP3 160 and certainly trumps MP3 128. I also found odd the fact that the slowest speed came for MP3 at 128kb. Maybe the AAC encoder in iTunes is better tuned for the G4/Altivec processor.

There was no call for that stupid, pointless remark. Go chat if you want to insult with banal comments.

Latest macworld (UK edition) puts the 1ghz iMac at 25% faster than the 800g4 imac. So that'd be about right. I suppose 7.5x is fine..still rips a CD in a couple of minutes. Just can never be fast enough.

Aww, I only get 20x AAC 160Kbps rip speeds and 35x 160Kbps MP3 rip speeds on my DP1250, sucks to be me. No really.
*NEWSFLASH* You have a slow computer.

Ok, your initial comment in this thread was so much more appropriate. You magically know all about my sex life? Interesting.
Funny that you're telling me to get off, Proxy, since it was an ignorant reply to your thread that started this... now you're defending the guy.
OK then, never mind me, and shut the **** up if that's what you prefer.
EDIT - adding the smiley, because this is funny really.... Proxy is madder at me for the humorous jab than he is at Mac Write for telling him to shut the **** up.
Kisses and hugs to everyone!! 8)

Careful about how much you brag, or Mac Write may kill you for your computer.

I just read this again and realized you are probably serious.
Thanks for the compliment. I'd like to think I could do that, too.
and as for being on a Beige G3, I am desperate for a new Mac, but don't have the resources due to being on permentent disability pention.
Oh and sorry Murbot, I didn't read it was you making hte laid post, or I would have reponded differnely (since your married).
a) AAC
b) QMusic Pro (v2)
(I know that QMusic codec is hugely better than MP3, so I am excluding this audio codec).
Q. What video codec produces better video output quality for QT?
a) Sorensen 3 (developer)
b) MPEG-4 (which is more universal)
Thanks for your thoughts on this.
