Wireless audio transmission system for real-time applications — A review

Since the past few years it has been observed that the technology is changing very rapidly. Many of the devices that we are using currently operate wirelessly. Therefore in this paper we have proposed a method to transmit the voice signals wirelessly using Bluetooth. Here we will use microphone or an audio device to input the voice signal to the controller that may be Arduino ATmega 328P. The controller is used to down sample/ up sample the data and finally a wireless device may be Bluetooth or ZIGBEE is used for wireless communication.
