Hi to all,

I hope that some one have experience with the iTunes MP3 ENCODER.

I don't know if iTunes use LAME or other encoder for MP3 but I have see strange setting in the setup page-

My setting are:

- STEREO BIT RATE 320 KBPS
- SAMPLE RATE: AUTO
- CHANNELS: AUTO
- STEREO MODE: JOINT STEREO

- SMART ENCODING ADJUSTMENTS ON
- FILTER FREQUENCIES BELOW 10 Hz

But what is the SMART ENCODING ADJUSTMENT?

And is not a bad idea filter the frequencies below 10 Hz?

What do you suggest?

For LAME I know that is better JOINT STEREO but with iTUNES ENCODER?

Thanks

I think that Joint Stereo, that is a lossless compression, can improve only the quality... I think that Apple has not clear what is JOINT STEREO... the same problem is present in DBPOWER guide, they suggest JOINT STEREO only for <160.

The only question is... the MP3@320 created by iTunes is good as LAME320?

I have dismissed XLD only because I want a "all one" program, with library and all into my PC...

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!
