Hi Rickey. I found a very large improvement in microphone audio quality by changing the resistor values shown in the datasheet. It shows 3 - 4.7K resistors surrounding the microphone. The top one that connects to Vcc, change to 1K. The other 2, change to 10K. Where the 1K meets the 1st 10K, you see a 4.7uF cap. Use a 220uF. Perhaps it was my microphones preference, but it was just a standard electret mic.
