and still the same bugs with mono input or "downmixing to mono"

mono files get converted to stereo, stereo files get doubled in lenghth when the "downmix" option is checked

i posted that thread, the downmix to mono option does work. Its just the file is mono internaly, but faad decodes it as stereo with both channels identical.

At the risk of repeating certain things: I wish they would provide incremental updates...
