But what is the SMART ENCODING ADJUSTMENT?
And is not a bad idea filter the frequencies below 10 Hz?
I have see that if I use SMART ENCODING, if I use JOINT STEREO in the MENU, the smart encoding OVERRIDE the choice and go with STEREO...
But LAME at INSANE PRESET will filter the 10 Hz Frequencies?
If you insist on using iTunes for MP3 encoding (not recommended, but even I do it in a pinch when I need something fast 'n crappy for the car, etc), I've found out several things of interest:1) Turn off "smart encoding options." It forces full stereo on anything higher than 160kbps, which as we know is very stupid. Turning it off allows joint stereo at any bitrate, which may result in an audible improvement at 192kbps and higher.2) Don't use iTunes VBR mode; it sucks. 3) Don't use anything less than 192kbps CBR. 4) As a general rule of thumb, iTunes MP3 encoder is so bad that you can safely figure on an encoding at x bitrate to sound similar to a LAME encoding at a step lower. In other words, iTunes 160kbps CBR is probably similar to LAME 128kbps, IMO. That's why I wouldn't suggest going lower than 192kbps, ever. If you follow these steps, you'll get a 192kbps+ CBR encoding that is more than good enough for a car, etc. Not LAME quality, but then again, I would never use iTunes MP3 encoder for serious encoding, even at 320kbps. The point is, iTunes is fast on a Mac when one needs a quick disc for the road, whereas LAME is slow; it's the difference between 3x and 13x! Again, only do this if you are in a pinch , and proceed at your own risk
I think that Joint Stereo, that is a lossless compression, can improve only the quality.
The only question is... the MP3@320 created by iTunes is good as LAME320?

I’m getting somewhere.QuoteThe only question is... the MP3@320 created by iTunes is good as LAME320?Theoretically? Probably not. In practice? Even with their differing levels of technical optimisation, the two encoders might not produce audibly different streams from any single source file, for the majority of material. A bitrate of 320 kbps has a good chance of being transparent, whatever the encoder. You can always test this for yourself with some tracks from your own collection.Someone with knowledge of historical comparisons between these two encoders, save me!
And the difference in the sound very much! She felt even at 320kbps. In simple Stereo sound is empty. In order to verify this is enough to compare the same track in Joint Stereo and Simple Stereo on normal (or high quality) equipment.

Joint Stereo does not create smaller files. Difference is only in quality of sound!
