It Was a Very Good Year

240 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 98% — put it in D minor, a key signature of 1 flat. The tempo printed above is the median of the 240 readings; 41% of them land within 2% of it, and the middle eight tenths of them run from 129.2 to 151.9 BPM.

At 135.4 BPM one beat lasts 443.1 milliseconds, so a sixteenth note is 110.8 ms and a dotted eighth 332.3 ms — the delay times for this recording. Counted half as fast it is 67.7 BPM, counted twice as fast 270.8. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440 Hz, which is 0 cents above concert A at 440 Hz — close enough to standard that a tuner would not argue. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 4.98 dB: that is how far the level wanders from its own average, so a small number means a loud, flat master and a large one means a recording that still breathes. Its average loudness is 0.414 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
