Hi, Bruce R if I can recall to get your extra codecs and programs lame, transcode ext. you need the restricted extras for ubuntu, easy way to get them. is in a console, code sudo apt-get install ubuntu-restricted-extras. (Depending on what ubuntu you are using, there is xubuntu- restricted- extras,and kubuntu-restricted-extras) make sure you get the right one. Dave.w

Hi dave.w 
Thank you for that advice, but I routinely install the Ubuntu Restricted Extras via Applications, Add, plus some other packages that I find useful, the best probably being Gnome Partition Editor, Sysinfo, VLC Player and NTFS Configuration, the latter for setting up retained desktop icon access to NTFS drives.
Even with those and other packages, soundkonverter won't cooperate, but fear not, I have managed to find out how to make Sound Juicer 'play ball'.
Every version's MP3 encoder obeys different GStreamer pipeline commands, but I have found how to make them reveal their list of commands and their syntax.
As a result, all on one line, with separating spaces I have now applied :
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc
mode=0 vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320
vbr-quality=3 ! id3v2mux
This results in ImageNEW EncSpotBasic's report of VBR encoding that is slightly better than Slipstreem's recommendation when using CDEX in Windows XP.
Once set, the Profile is retained and ease of everyday use of Sound Juicer then applies. You can even set it to 'spit out' the CD and display the destination Home / Music sub-folder MP3 contents at completion of fast encoding !

Well done, Bruce!
It's getting there. The encoding is quite clearly in VBR now, but there's still one thing missing. Joint stereo.
The extra bitrate that's being used when compared to the standard -V3 setting is actually being swallowed up on processing the audio as two discrete audio channels. It's not going towards increasing quality. Standard stereo always requires twice the bitrate to store audio when compared to an equivalent mono source and is the least efficient method available for stereo encoding.
Joint stereo is a lossless process in itself and has no effect whatsoever on the stereo field when compared to discrete stereo. It allows the encoder to seamlessly switch between L/R stereo and M/S (mid/side) stereo choosing whichever provides the most efficient encoding method on a block-by-block basis.
It behaves in such a way as to store the channels as discrete left and right signals when this is calculated to be the most efficient method. However, when it requires less bits to store the audio data as sum and difference signals, ie, when the signal contains a higher percentage of mono than stereo content, M/S stereo is used to store the block in question.
The net result is audio that sounds identical in every way but requiring a lower bitrate in VBR mode.
Joint stereo is also the default for LAME VBR encoding, so I'm not quite sure what's disabling it, but you'll definitely benefit from invoking the required switch to re-enable it. The file being produced still isn't standard LAME VBR without it.
Cheers, Slipstreem.

Hi Slipstreem
That's finally cracked it then, because that was the only setting that I just took a guess on, leaving it at its default. Changing mode=0 to mode=1 invokes joint stereo. I'll do that and add a revised FinalImage report to this post ! 
Edit PS - Now attached to this post are Image2, for the CDEX produced file and ImageFinal, for that now produced by the finally modified Sound Juicer 2.22.0, with the following GStreamer pipeline settings for 'CD Quality, MP3'
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=1
vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320 vbr-quality=3 ! id3v2mux

I do believe you've totally cracked it, Bruce!  The small remaining difference is most likely down to the use of different versions of LAME. Both 3.97 and 3.98 are recognised as being excellent performers, so it's entirely up to you whether you update to 3.98 for use under Linux or stick with 3.97. The only parameter that requires changing for different quality levels is the one that selects the -V level. Everything else remains constant down to -V7 where the samplerate is usually dropped to 32kHz from 44.1kHz. I admire your perseverence. Cheers, Slipstreem.

Excellent.
It's been very rewarding to be able to offer some help in the Linux forum for a change. I have no idea what you guys are talking about most of the time, but it's nice to know that we speak a common language in at least some areas.
Enjoy the fact that LAME VBR is now working exactly how it should, and please do spread the word.
Cheers, Slipstreem.
EDIT: PS I wonder if it might be worth adding the word "RESOLVED" to the topic subtitle for the first post? It would make it considerably easier for people to find a workable solution if using the forum search option.

Just to let folk know that Ubuntu Restricted Extras and Sound Juicer can be added to Mint or Intrepid and then modified in the same way. (Opening Post so edited.)
