For those interested Swedish Radio has a page with demo files of their new programmes using multi-channel technology*. File can also be used to test the surround setup and the quality of Windows drivers. They work only for sound cards that bypass kmixer. Files ca also be burned into an audio CD and then played the usual way. I have downloaded the Stravinsky's Firebird in DTS (1.5mps stream) and was extremely pleasantly surprised with the quality and the surround effect. This looks to me the right way to go for multi-channel programming. Much better than SACD or DVD-A routes. * Moderator please note that the copyright owner allows free distribution of these files.
