A thought came to me the other afternoon-- do you have sound effects running in the background, appropriate to the 'room?'
May I suggest the album, “Star Trek Original TV Series Sound Effects?” It has several SFX tracks from TOS episodes, including some from The Cage (including the ‘slow’ transporter effect).
–Paul E Musselman
ps-- the background effects in the transporter room and on the engineering deck sound a lot like a poorly-bulk-erased reel-to-reel tape recording captured while the tape was winding or rewinding!
pps-- The album, “Time Warp,” by Erich Kunzel & the Cincinnati Pops Orchestra includes 2 tracks of interest-- Jerry Goldsmith’s “Star Trek: Main Theme” from the movie; Alexander Courage: “The Menagerie (Suite)” from the original pilot for the TV show.
