I took the setting where the artifacting disappeared on the most difficult sample and upped it one notch, just to be safe. That came out to AAC 256 VBR.


This is kind of off topic, but there's some tests that have LAME mp3 coming out slightly clearer around the 256 kbps range than AAC.

That's the first I've heard of that. Do you have any more information? I'd like to explore further.

I'll go find the posts on another forum detailing this. Unfortunately the forum is private, so I can't directly link to it, but I'll copy the information and start a new thread.

In my comparison, MP3s were about one notch below AAC, but I disn't encode LAME. I doubt that there's much difference at 256.

 

I don't know if phase inversion of pure tones is necessarily the best way to test. Codecs seem to not struggle with pure tones as much as sophisticated textures of sound like applause or massed instruments.

AAC @ 256 VBR turned out to be the sweet spot for me, as well.  I probably could have used 224, as it too sounded quite good, but I bumped it up a bit just to be safe.  As far as LAME goes, for the most part it sounds the same to me.  I use AAC for my computer and portable listening, but I also transcode to LAME V0 for use with Google Music (from the ALAC rips) so that the AAC files don't get transcoded upon upload.  I didn't really hear a difference, though there were a few instances that I thought AAC sounded a little better.  But that's just me.
