hi mesnik, i'm afraid not, although you could easily "cut n' shut" the 25-50 and add the word thousand to the end of each amount from a thousand announcement, I experimented and made a 12,000-24,000 but I didn't have the finesse to make a good job of it, so it sounds rather tatty compared to the others, which is why it is not included on the thread.
I was using Cool Edit Pro 2, but i'm sure there will be better programs around for editing .wav's
Regards
Stuart
