Speex has a 2.15 kbps mode. It doesn't sound very good though.

It's written in C, but it's not (yet) entirely in fixed-point (integer).
Most of it is converted (the higher bit-rates are entirely fixed-point),
but there are a few float ops left IIRC.

Yes, if you convert the rest of the code to integer.
