Sah-weet! I had looked at ecasound before but I though that it didn't do what I wanted, since it only offers a way of controlling the mark-in and mark-out point on the source file (to borrow video-editing parlance), not the mark-in on the target. However, when I grovelled about a bit more, I found that the .ewf file format is exactly what I wanted. Many thanks to you, Graham, and Eric for your help!
