FHG mp3 VBR with JS?

Anyone knows Fraunhofer MP3 encoder implementation that actually uses Joint-Stereo when encoding in VBR mode?

If i remember right the Cooledit Pro plugin was of this kind. www.ff123.net has plenty of info about older fhg codecs. You may have a look over there.

I remember the one from the recent MP3@128 pre-test discussion.

Thanks for the tips, the CoolEdit plugin (MP3 Me) does not use joint-stereo in VBR. MMJB uses Joint-stereo, but the mp3s encoded by MMJB with joint-stereo actually sound worse than those encoded with CoolEdit with simple stereo (at the same bitrate)! This is weird.

Just a bit off-topic:

Why are you interested in FhG?
As for me I was interested in FhG behavior now that there is a real-bad pre-echo sample out there (eig).
However none of the FhG encoders I tried do a good job on it even at cbr 320. My Lame favorite (3.90.3) to me performs as well using --alt-preset 270.
Moreover from my other favorite problem samples harp40_1, herding_calls, trumpet I know FhG's VBR behavior is pretty bad.
So I'm a bit disappointed about FhG Encoders.

At the moment I do intensive tests with Helix which has a very good VBR behavior, in general and especially with 'my' bad samples, and an unusal good pre-echo behavior compared to other mp3 encoders when it comes to eig. It's good to me already with -V120 (~200 kbps) and level's setting, and even better with -V150. Unfortunately Helix' HF behavior isn't perfect and I'm about to find out what this exactly means.

I am interested in FHG because I like its VBR quality at medium-low bitrates (~100kbps). I am sure that with properly implemented joint stereo it should give some respectable quality.

I think I found answer to my question: FHG encoder probably incorrectly states in the header that the file is in Stereo mode. When you run the file through vbrfix, you will see that its actually Joint stereo.

Exactly which FHG encoder are you using?

You might want to check out XING v1.5 at -V 30 (maybe even -V 50 without sfb21 will be that low of a bitrate.. if you can find the encoder  )  I still prefer lame 3.93.1 at ~100kbps, but I would like to compare that with the encoder that you seem to like.

EasyMP3's implementation of FastEnc. I think CoolEdit Pro with the MP3 plugin works well too. You can use the "fastencc" from Rarewares, but it has nasty stereo bug in VBR (quite rare but you will know when it comes) which cannot be fixed with the "-hq" switch. The particular setting I like is this: set bitrate to 112kbps (adjusts lowpass) or 128 kbps if you like more high frequencies, set VBR level to 30 or 25 (around 105kbps)
