J-Stereo and I-Stereo

Someone can tell me the difference between Joint Stereo and Intensity Stereo?

Why I-Stereo isn't supported by Lame 3.9x?

Will it be supported by Lame 4?

Why do u care about intensity stereo?
From what I know (I might be wrong...) intensity stereo sucks.
Wanna buy a monkey?

Excellent explanation, yourtallness.

IIRC, IS is really a mono stream with directional info - to 'emulate" a stereo effect.

JS is 2 strems, and some frequencies are shared, if I'm not mistaken.

Lame doesn't supports IS because it's targeted at high quality, and IS is only useful at low bitrates.

Takehiro plans to implement IS on Lame 4.0, IIRC.

Well,i'm reading here

http://www.hydrogenaudio.org/forums/index....ST&f=16&t=9238&

and Takehiro writed

"Intensity stereo is "must" item before public testing, but it is completely new code and it takes long time to finish implementing.

ABR/CBR noise shaping code are almost finished. But bit resovoir code need to be tuning for short blocks and lower bitrate. This tuning will start after implementing i-stereo."

so i'm a bit curious..and i'm waiting to something that explain me the difference between I-S and J-S

Tnx for the explanation 

"IIRC"...what does it mean?

i thought intensity stereo would switch to mono if a strong signal was in one channel? (assuming i guess that you couldn't hear the other channel anyway)  Maybe I'm wrong, there isn't to much talk about IS on these boards.

Thanks for that description of IS, Gabriel.  Makes alot of sense now.
