Hybrid Multichannel SACD mastered by Doug Sax and overseen by Bruce Botnick, The Doors producer/engineer.
The surround sound program on the Doors SACDs comes from the original 96K, 24-bit files mixed and mastered by Bruce Botnick for the DVD Audio Doors/Perception release. Those mixes were made from the original one-inch, eight track, 15 i.p.s. analog master tapes. For the SACDs, the mixes were then up-sampled without filters to DSD using the Weiss Saracon format converter and authored by Gus Skinas at the Super Audio Center.
