2 Ways to Play Audio using a Microcontroller - Embedded World
http://www.raviyp.com/2-ways-to-play-audio-using-a-microcontroller/
The record and play control functions are controlled by microcontroller IO pins. These chips have inbuilt pre-amplifier, so that you can connect the microphone directly to the chips input pin. And also come with inbuilt output audio amplifier, so that you can directly connect an speaker to the audio output of APR9600 chip.

Audio signals meant to go between equipment but not directly from microphones or meant to drive a speaker are usually at line level, which is usually around 1 V RMS. That is about the right amplitude for driving a microcontroller A/D input, but the DC level needs to be set close to half of the A/D range. This is what R2 and R3 do in this circuit.
Arduino Microcontroller Audio Control

Audio Tone Generator using AVR Microcontroller. The circuit presented here demonstrates how to generate Audible Frequency from an AVR Microcontroller. The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose.
