Not if you're unsure about which channel to read from:

(call-with-output-file "test.ascii" (lambda (p)
   (let ((r0 (make-readin "filename.wav" 0))
         (r1 (make-readin "filename.wav" 1)))
     (while (and (< (mus-location r0) (mus-length r0))
                 (< (mus-location r1) (mus-length r1)))
       (format p "~A~%" (if (= 0 (random 1)) (r0) (r1)))))))
