Yes you seem to be right, just checked twolame source and it seems to
convert from float to short with float32 calls.

I was more thinking that if there is channel count/resampling done, fl32
is used as format and with this you wouldn't need to convert back from
that. But as it seems twolame seems to do it anyway. Thanks for pointing
