No. These PDAs (and similar ones) do not have floating point hardware. Without 
that (i.e. using software-emulated floating point), this cpu is far too slow. 
No fixed-point vorbis _encoder_ exists, currently. So there's no chance at 
all with vorbis, unless you want to write such an encoder (this is a Very 
Large Task).

For mp3, it might be possible. I think fixed-point mp3 encoders exist, though 
they're not (afaik) competitive on quality with things like LAME, and there 
may not be any free (non-commercial) ones (you'd have to pay the mp3 
licensing fees anyway). You'd have to investigate.
