You cannot do this using standard unix commands. There are many utilies
for sound recording (bplay, brec, vplay, vrec ...).
You can set the sample rate and the number of bits and enable stereo using
some ioctls named SNDCTL_*.
You can find them in the ioctl_list man page.
For example you can use SNDCTL_DSP_SPEED to set sample rate.
