Thanks for the steer, Simon. Had quite forgotten about Audacity which I use regularly if infrequently. A great program with more features than I will ever use. I believe the speed changer will be fine though I've gotten mediocre results with Pitch Change and poor with removing the vocals from a music piece. Understandable this since the signals are all buried together in an analogue single track recording
