Note: I don't know if it is a fault of the tape or my reel to reel player, but the audio plays back at an extremely high rate. I fixed this in audacity by decreasing the speed by 48% as decreasing it by 50% made it sound too slow.
Reel To Reel players have several recording/playback speeds - typically, single speed home machines play and record at 3 3/4 IPS (Inches Per Second), but higher quality ones had a 7 1/2 IPS option - and professional ones use 15 IPS.
