wavewrite / wavread and 32bit float wav file

[Rick T]

Greetings All

I was reading some of the specifications for waveread and wavewrite (in octave) and it says the maximum is 16bit sound files.  Is there another function to get octave to read and write 32 bit float wave files?  PS I'm using octave 3.2.4 (from the repos) and ubuntu 12.04

Thanks
