Next setting of new Lame mp3 encoder (3.98) to be tested at SE is “–V 0” – the highest quality VBR mode of the encoder. Resulting in 231.9 kbit/s on SE test files it fell into 224 kbit/s group. As usually first reliable results are expected in a week or two. But you can help SE to improve some of its green (grey) ratings faster - just take part in testing … if you want.
