Paul, two questions:
1. Has your wife's recording room been acoustically treated?
2. What is your (or your wife's) budget?
No we haven't got a treated room, best bet looks like the study which has a wall of bookcases.
Budget is as cheap as possible as we don't know how much work this will lead to.
Things moved on a little. After going quiet on Monday my marketing department came back and said could we do it now! Ended up recording on an iPhone as that was better quality than my laptop. Feedback is that, with some post production, they can use it.
