[CM] moving-autocorrelation

[James Hearon]

Hi,
I'm struggling with trying to view data returned from make-moving-autocorrelation.  The manual indicates data is available from mus-data, but I'm only seeing zeros if I'm doing that correctly.  Moving-pitch, etc. work fine.  Just can't seem to see anything from moving-autocorrelation.

Regards,
Jim

(let* ((n 512)
         (hop 128)
         (ac (make-moving-autocorrelation (make-readin "/oboe.snd") n hop ))
         (mydata (make-float-vector hop))
         )
(format #t "mus-data:\n")
(let* ((data  (mus-data ac))
       (len (length data)))
(format #t "length data: ~A\n " len )

(set! mydata (mus-data ac))
    (do ((i 0 (+ i 1)))
      ((= i hop))
(format #t "~A ~0,12F\n " i (mydata i) ) )))
