Thanks for the interest in these discs. Great to find out more. I wonder if Shai uses Diamond Cut software for this task? I used to use DC6 to correct for speed changes that were pretty linear and slow, e.g. batteries dying in portable cassette recorder used to record a professors lectures. That was like eight years ago though! Haven't had such issues to deal with since then, and I now see Diamond Cut is up to version DC8. -Karl Karl Fitzke 607-216-8070 forwards to other numbers below Karl, Aileen, Joe, & Nick Fitzke 202 Rachel Carson Way Ithaca, NY 14850 607-280-8705 mobile 607-254-1100 work 607-277-4742 home On 1/6/16 6:38 PM, Ellis Burman wrote: > Hi Shai.
