Notes:
*Two incomplete fragments from different sources joined together at ~26:47 of Sometime Ago
-The joining of the segments was done earlier in the lineage, and I suspect it was done in the analog domain
because the phase and speed error was the same where the parts were joined
-the audio has very limited bandwidth and not a lot of crowd noise - I think the second source sounds a bit
better but not substantially and it occasionally has some weird noises in the background

-phase corrected the channel alignment by 5-7 samples
-the necessary fixes for the pitch/speed error were odd: the first ~25 sec was 2% slow on average (with rapid
fluctuations that I cannot fix), but then it suddenly became on speed after ~0:25, then at ~02:25 it suddenly
become 2% fast. Then it gradually got faster, ending 3.3% fast.
