Of course the question was about recording, not playback.  But there 
were several machines like Joe mentions, such as the Duophone.  Some had 
a horn on either side of the diaphragm -- which would provide sound that 
was out of phase in each horn and could slightly cancell each other out 
if pointing in the same direction -- or that used a dual reproducer 
which had the two styli an inch or so apart to provide an echo effect.  
Lastly is the famous Coloumbia Graphophone Multiplex Grand which used a 
large cylinder with three horns and three recorders/reproducers.  This 
was capable of three channel stereo in 1899.
