Audio Talkback Recorder on Arduino

Write a C programming with Arduino micro-controller. Audio must first able to be captured from a mic then pass through an anti-aliasing bandpass filter and analog to digital converter (ADC). When the audio reached the micro-controller, it is stored into SD Memory Card and also do signal processing to the audio (like increasing the pitch or speed of the audio). Stored audio will be shown on a LCD panel for user to choose from using push button and play it. Lastly audio will pass through a Digital to Analog Converter and play it from a microphone. Hence my coding must include audio recording from input mic, anti-aliasing bandpass filter, Analog to Digital Converter, Digital to Analog Converter, Store audio into SD Card and multiple signal processing algorithm like (windowing, echoing and other effects) and able to play it at the speaker output. Comment must be written on every line of code.
