My Microphone Troubles

Good afternoon,all.
Could anyone here give me some suggestions ?My situation is as following:
Hardware: STM32F405 hang a mems to analog microphone,audio acquisition , wave filtering, amplifier and feedback.
Software: SCM recording, sampling, quantifying, coding and then producing PCM data,then leading PC into PCM file and playing it by cool edit.
Qualification: what’s be collected is voltage value.
Coding: These voltage values produce eight binary system and save in pcm file.
Could anyone tell me what’s wrong? I am considering about that can I use this chip--TLV320AIC32 to solve problems? Have you use TLV320AIC32 ?

Thank you in advance.
Best wishes~
