In response to Gale: yes, you are surely right that the BEST way is to record the audio without clipping in the first place. But as I mentioned, I've found many posts online from folks in a similar situation to mine: The recording cannot be made again because the event is over and if we want to share it with others we are stuck with this recording. Based on my manual deleting, I KNOW that a much better product can be made by deleting the largest spikes -- but as I said, that process must be automated to be practical. I also agree that using EQ to magnify the portions to delete (the spikes seen in screenshot 3) is not 'ideal'. But I want to emphasize that for simple speech it's not necessary to have 'ideal' sound -- but it is necessary to remove glitches that hurt your ears, and that's all I'm after as the person who wants to 'repair' this audio.

In response to Koz: I guess you could say that I request 2 things in my post: (1) Being able to "select" all the data points which are highlighted when one chooses View-->Show Clipping. Once selected, you could then press "delete" and they'd be gone. (2) To be able to set a horizontal threshold above/below which data points would be selected -- thus the spikes of screen shot 3 (which is where all the unpleasant glitches occur) could then be removed by pressing "delete". I can do both (1) & (2) manually, but it just takes forever.

Thanks for all the great help, and so quick!!

Tom - This is exactly what I am looking for also. Would greatly appreciate if you found a programmatic way of doing it. Thanks in advance!

  (setq threhold 0.95)
    (setq frequency 16000)

    (let* ((control (rms
                      (sum (- threhold)
                        (s-max (snd-abs s) threhold))
                      20))
           (gain (/ (peak control ny:all)))
           (control (mult frequency
                      (sum 1
                        (mult control (- gain))))))
      (lp
        (lp
          (lp
            (lp
              (lp
                (lp
                  (lp
                    (lp s
                      control)
                    control)
                  control)
                control)
              control)
            control)
          control)
        control))
