I have a tape of a lecture from the early 1970s that I am transcribing for a book. Since nobody had an old analog dictaphone handy, I just digitized it using Amadeus II, and now I have a QuickKeys macro that pauses and starts Amazing Slow Downer.

It is not as convenient as using a foot pedal to start/stop/change speed, but it works well enough. Now, if only I could get used to deciphering a Scottish brogue played at about 25% of normal speed...

I am getting some "Can't read file errors" after frequent stops/starts and rewinds, but I'll check with Roni Music on that.
