I've been using Express Scribe for a few weeks and each time I lower the speed past about 90%, which ain't all that slow, the sounds distorts to the point of it being unintelligible. I transcribe a lot of French-language stuff and sometimes I need to be able to slow them down more than Express Scribe allows me to. The help guide suggests that 50% should be doable, but I can't see how. Anyone have any suggestions?
