when it is actually striking/when it actually strikes

On the B.B.C. you can hear the clock (Big Ben) when it is actually striking because microphones are connected to the clock tower.

(New Concept English 2, Longman)

I wonder if ‘when it is actually striking’ could be changed to ‘when it actually strikes’. If so, what’s the difference between them.

Thanks a lot in advance.

    I think the continuous tense is better there, because when Big Ben strikes, it takes quite a few seconds and so the sentence implies that you can listen to the whole thing from start to finish. :)
