This show comes to us as a master cassette tape. It was digitized using 32-bit format and 24-bit resolution. Analysis revealed music signal up to
11,000Hz. The complete show is here so no patches were necessary but the tape flips and change from tape 1 to tape 2 needed to be mixed. The taper
provided us with the details regarding his location in the audience as noted above.
Hiss was a moderate problem that was reduced using selective techniques. Crackle was also present throughout the show and needed separate
techniques to be reduced. Given the frequency response of the recorder, the midrange was too harsh so filters were applied to reduce this excess. An
imbalance between the two channels was present and a 12% correction was necessary. The mix does change through the show. During the first few
songs the sound, and in particular the vocals are a bit distant even though we know the taper was in the second row. This improves by the time Cruise is
played. Applause was attenuated where necessary and other noises such as feedback, clicks and pops were removed. The show was then tracked,
converted to 16-bit and placed in audio format.
