The bitswap was meant as an intermediate solution. The proper
solution will be extending the voice file header with a format
and target indicator, and building target specific voice files.
This does not only mean to avoid the bitswap, but also to
exclude voice clips not needed for a target, and to be able to
use a dedicated voice codec (i.e. speex) instead of mp3 for
swcodec targets. Unfortunately we still don't have a speex
codec, in spite of a lot of talking about it...
But for now, I don't think the bitswap is a big problem. It's
done only once when the voice file is loaded.
