I am endeavoring to make available 5.1 surround sound mixes of some of my songs. These songs will be available, for free, at my website: http://www.alaska.net/~hammy/hammytech/ac3.html
There are currently 20 songs posted and I plan to have more added when I get finished doing the 5.1 remixes..
The songs are in the .ac3 format, which is the standard Dolby Digital surround sound format. They are true 5.1 mixes with a center channel, front stereo, rear stereo and LFE ( Low Frequency Enhanced = subwoofer) channels.
