Whole house audio has become easy. The cornerstone of modern audio system is the DAC (digital analogue converter). The DAC will convert an audio stream from a computer (such as a Spotify account) into an audio output. As well as the DAC an audio system needs speakers and an amplifier. These three components may be packaged together into one unit (such as a Sonos Play) or split into 3 separate units. Normally, for building installation the DAC and the amplifier are located in a central accessible location and the speakers are in the walls or ceiling of the room.
