Sorry, I just noticed my idiocy: this should probably be
avctx->sample_rate / 2

But it does not work... :(
(I mean, "-ab" does not have any effect on the final bitrate)

Reducing the faac_cfg->bandWidth value a lot (something like
avctx->sample_rate / 8) does work...
Any suggestion about a proper value for "bandWidth"?

			Thanks again,
