Hi all,
in many discussions I read about mp3 via Lame encoder the result is that the best solution is joint stereo. I believe in that as the developers who I highly esteem say so. But is this statement supported also by more independent listening tests? Especially I would be interested in comparison between --preset standard (joint stereo) and dtto with stereo mode. Can the result in general depend also on the Lame version? From the tests I could read usually still the old good Lame 3.90.3 comes out as the winner. Cheers, Crazyman |

This makes no sense, since joint stereo is just a way to encode stereo losslessly.
There should be no audible difference between them AFAIK.... -------------------- http://volutabro.blogspot.com

No, joint stereo is lossy. That's what directed the Scene to use full stereo mode (not that they really know what they are doing). But joint stereo can be objectively transparent if implemented properly...and it can save you a lot of bits. There is generally no need to use full stereo in LAME. |

No, Joint Stereo is lossless concerning stereo information. Some scene groups are using 'full stereo' VBR, because using a Dolby Pro Logic or similliar surround DSP will unmask JS artifacts, which are masked under normal (=stereo) playback conditions.
