The circuit schematic drawings Surround Audio Decoder and its components and how to make it ,Audio surround decoder circuit. Surround sound quality is the process of adding the audio source by increasing the number of speakers. This is done by producing audio multitracking in a way that can be issued on a multichannel speaker.
Basically surround adopt an existing stereo system. The system uses a two-speaker stereo is right speaker and left speaker. With two speakers will be three-dimensional effect of the sound issued. With the surround, which generated three-dimensional effect was more extensive than in stereo. This is because the surround speakers that use more than two pieces. In addition to supporting the three-dimensional effects, stereo field theory is also noteworthy to organize the arrangement of sounds based on the type of sound produced.

Surround effects can only be listened to speakers who have more than two channels. Surround is a technique commonly used in today's films that utilize multichannel speakers. Surround allows voice can move from side to side, is a moving side to side is to move from one speaker to another speaker. To create three-dimensional sound effects you can use a series of audio surround decoder.
