The link up has been expected for some time after Baker posted on his forum that he was in talks with the company, but noting was officially confirmed until a press statement from the company earlier today.
Baker has previously recorded a set of stories for BBC Audio, but has never worked for the independent company before.
The new adventures will be recorded this summer and are expected to be released early in 2012. A first season of six single-disc releases will released, with a second season of seven single-disc releases to follow at a date to be confirmed. There will also be a five-disc box set entitled Doctor Who: The Lost Stories – The Fourth Doctor Box Set.
The producers across the Fourth Doctor adventures will be David Richardson and Nicholas Briggs who said
As many of you will know, we've been talking to Tom for a long time, David Richardson and I went to visit Tom at his home not long ago to chat about it all. We had a really great time. At that point, I sincerely felt that had we taken a microphone with us, Tom would have started there and then - but, of course, there are always finer details to sort out. Now that our plans are in place, and Tom has enthusiastically told the world that we're going ahead, we thought it best to follow-up with our own announcement. Rest assured that in the coming months we will be releasing news on this as soon as we are able.Executive producer Jason Haigh-Ellery said:
I am delighted that Tom will be joining the Big Finish audio adventures of Doctor Who. As a small child, I remember how charismatic and engaging his performance was each Saturday tea time - and we are all looking forward to recreating that era again.
