I'm glad to hear that my data size can be shrunk considerably, however I do not know the minimum values that I would set the static arrays to be. I hate to be a bother but could you tell me the minimum values for these arrays/structures in the state structure?

Hi everyone, As you may have guess, Speex 1.2 is slowly approaching, though there's still a lot left to do so I can't say how long it'll take. I thought this was the right time to ask if there's anything missing or that can be improved to make 1.2 better. At this point, it can't be anything major, but there are still some changes that are possible, e.g: - Improving some
