Yes, quite a few:

-b N    sample frames (or -kprds) per software sound I/O buffer
-B N    samples per hardware sound I/O buffer
-A      create an AIFF format output soundfile
-W      create a WAV format output soundfile
-J      create an IRCAM format output soundfile
-h      no header on output soundfile
-c      8-bit signed_char sound samples
-a      alaw sound samples
-8      8-bit unsigned_char sound samples
-u      ulaw sound samples
-s      short_int sound samples
-l      long_int sound samples
-f      float sound samples
-3      24bit sound samples
-r N    orchestra srate override

Are the options that would be relevant in this case. Any ideas on what 
to go for???
