This sound.cfg replaces the one uploaded in August 2008. Both the interior and exterior sounds have been improved. Please replace the sound.cfg you already downloaded by this new one. In my search for a good sound for the Douglas DC-6/-6A/-6B/-6C, XC-112A/YC-112A, VC-118, the C-118A/R6D-1 series and the Canadair C-5, I struck on the fabulous soundpack for the beautiful Douglas A-26 Invader of Milton Shupe and the Sim-Outhouse Team, made by David C. Copley. Most of the wav-files in this soundpack are recordings of the Pratt & Whitney Double Wasp R-2800 engines of an A-26 Invader. Having studied the Invaders sound pack, I discovered that by ?tweaking? the sound.cfg, particularly with regard to the exterior sounds, it became possible to develop a good exterior DC-6 sound (4 engines). No changes were made to the wav-files, as I didn?t want to modify them; the wav-files just sound wonderful. In order to make your system reproduce the DC-6 sound, first download from www.sim-outhouse.com the great Douglas A-26 Invader package and enjoy flying that plane. Then copy the sound pack of the A-26 to the DC-6, and replace the existing sound.cfg by the revised one you just downloaded. This DC-6 sound has been tested in FS2004 only. Special thanks to David C. Copley who gave his permission to upload the modified sound.cfg as freeware, with limited distribution, at Sim-Outhouse.com and Avsim.com. Many thanks also to Milton Shupe and to Wayne Tudor for his advise. Author of the original sound pack: David C. Copley. Modified sound.cfg: Maarten Brouwer.
