Because someone asked for it, here is foo_asap v0.2.1.
It is designed to work with foobar2000 0.9x.
Whilst I was upgrading the plugin, I fixed the multi-instance issues that was plaguing the underlying playback engine (you can now play and encode at the same time). Unfortunately, as a result of this update, I believe I have introduced some playback issues (songs missing some notes, badly formed music, poor samplerate conversion).
Sorry, I haven't yet written a manual yet, but hopefully, the plugin should be quite straightforward to use.
