In SDL, the conversions are always done in place, which means you might
need a bigger buffer than the original data needs (since changing from
mono to stereo would need twice as much space).

In SDL, len_mult is never less than one, but it is frequently greater than
it. If the converted data is smaller than the original, you couldn't
shrink the buffer anyhow, since the original needs that whole block of
space, and thus, len_mult would be one.

I'm not sure I'm answering your question, though.
