You were told that it was a “possibility”. At that stage we had not heard even a single sample of the problem and you had not updated the sound card drivers (which was one of the first things suggested but you would not do until a further 6 pages if needless correspondence). We still have not heard any examples of your microphone recording so we have no idea how good or bad it is and whether changing hardware or changing anything else will be of ant benefit,
You already know this, but for the benefit of any newcomers to the forum that may be reading this, that is totally untrue. Your question was answered at least 6 times by at least 3 different people. If you need to refer to the previous response you will find them here: PITCH OF VOICE PROBLEM (SOLVED)
I wasted around half an hour writing a detailed answer to your question about sample rate and bit depth. That is half an hour that I could have spent helping someone that could be bothered to read my reply.
You have wasted enough of everyone time with this.
