Playing iTunes' AAC-encoded music on a PC
Authored by: Anonymous on May 13, '03 03:55:37PM

sounds like you're using the iTunes encoder. LAME is much better. use it along with the "Encode with LAME" applescript. i use the "--r3mix" tag which yields high quality VBR encoding.

the problem with your 160k setting is that it sets the minimum encoding rate, which is silly. if you have a stretch of silence, why encode it at 160k/sec?

with LAME and "--r3mix", my files average 160k/sec, but the individual files can range from 100 to 230.

as for AAC encoding, from what i can tell, its not there yet. mp3 encoders have recieved a lot of focus for quite a while and AAC is just now being used as an MP3 alternative.

That's not totally correct.

A VBR MP3, at least when using LAME, will ignore it's base limit if there is silence. Use the histogram to watch how it encodes an MP3 with a hidden track, so there is a length of silence between the two songs on one track. It will not stick to 160k, but jump down to 32k packets until there is something to encode again. Unless you use the -F flag to "strictly enforce minimum bitrate".

I will agree wholeheartedly that after many MP3/AAC encoder shootouts using LAME 3.93.1 and QuickTime AAC, the LAME still sounds much better. I think the AAC codec has promise and could potentially be much better than MP3, but the QuickTime codec stinks.

But then again, I'd rather have a bigger/badder iPod and just store AIFF files anyway. That's another story altogether.

-r3mix is an old setting, not taking the advances of lame in recent years into account. -alt-preset-standard is the current recommandation for lame
