== Description ==&lt;br /&gt;
&lt;br /&gt;
FreeSurround Decoder decodes surround information from stereo music, and produces multichannel output from it.&lt;br /&gt;
&lt;br /&gt;
The decoder should be compatible with the following coding schemes:&lt;br /&gt;
* Dolby Surround&lt;br /&gt;
* Dolby ProLogic&lt;br /&gt;
* Dolby ProLogic II&lt;br /&gt;
* SRS CircleSurround&lt;br /&gt;
* SRS CircleSurround II&lt;br /&gt;
* DTS Neo:6&lt;br /&gt;
* Lexicon Logic7&lt;br /&gt;
* Stereo Quadrophonic (SQ)&lt;br /&gt;
* Quadrophonic Stereo (QS)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
SQ is decoded with mono surrounds (i.e. like ProLogic I), due to a defective coding specification.&lt;br /&gt;
&lt;br /&gt;
QS requires the front stereo separation to be set to 1.5, or else the sound field will be too narrow.&lt;br /&gt;
&lt;br /&gt;
