I don't know what proper phrases might be, but I'd like the ability to jump ahead, say 30 seconds, or go back 30 (or other amounts...just tossing out a number).
I record some radio shows, and would like to be able to basically rewind and hear something again. Maybe I didn't quite understand what s/he said, or I just wanted to reinforce the idea.
Say I listen to a local radio show on gardening. They have call-ins. Someone calls in to talk about maple trees. Not interested. I can skip ahead. Then someone is talking about pruning roses. I'm interested, and they said something I missed. I can go back and hear it again.
If this exists, I'd love to know how to do it. I know it works on podcasts, but some of these shows I listen to have no podcasts.
