MP3 or AAC/MP4

Just talk about kJams stuff with each other, describe things you did that worked, talk about your setup, anything that doesn't fit into the other forums!

MP3 or AAC/MP4

Post by randyj »

I know this is a religious debate, but...
I'm about to rip / import almost 200 discs, so I'm deciding on what format to use.

I'm leaning toward mp4 / AAC right now, mainly because it's so much FASTER than mp3 to rip a disc ... like 2x faster (the encoding process is like "instant" on Intel Core 2 duo)

Please share your reasons why I should go with MP3 instead

thanks! :)

can you use AAC+CGG files on any windoze software? not that like you'd want to, but some people prefer interoperability, and MP3 certainly provides that.

the next version will work around this problem by not bothering to set meta on QuickTime.mov files. (i'll still store it in the xml file next to the song file, so kJams can read it)

just out of curiosity (I'm not a cat, so it's ok... I won't die)

:)

Why is it that importing a song in MP3 seem to take INFINITELY longer than MPEG-4 (AAC-LC) ?

15 seconds in AAC, 32 seconds in MP3, same song, clear cache both times

CC: "infinite" is an American term for anything lasting longer than 30 seconds :wink:

AAC has been hand-tuned by Apple to use AltiVec on PPC and SSE on intel. LAME has not.

i'll look into hooking that into LAME

AWESOME?

I had to look that up too.

Awesome: Adjective:- American word meaning "quite good".

thanks for the quick AAC fix :)

But... I got to thinking... you're right. I should use MP3 because that's what everyone uses. If the Mac or kJams goes away, I don't want to have to re-rip.

The only attraction to AAC is that it rips a disc like 2x faster than MP3 and I'm facing a stack of BAZILLION discs which will take an INFINITY to rip, and as long as I'm spending the time, the track should be AWESOME...

This is why I'm procrastinating.

don't procrastinate waiting for me to hook up the SSE / Altivec to LAME, that probably won't happen soon.

*CC rubs his whiskers*

I perceive that I was still in your thoughts as you typed this. I am fascinated by the language that you call English in your country.

"Bazillion" does as you know mean a number larger than six.

"Infinity" you assure me means more than 30 seconds.

"Awesome" I have come to understand means quite good.

"Totally Awesome" I gather means good or perhaps really good.


There is also the word "Ton" as in "Apple have produced a ton of software". In England not much comes by the ton. Maybe coal or concrete but not software. So I am looking for a reasonable definition for the word.

e.g.

Ton: noun :- American word for an unknown number greater than two but less than a bazillion.


:?

Will that serve or do I have it wrong?

Yes a Ton is less than a bazillion. And i have produced tons of code. But not a bazillion.
