A New Machine, Part 2

162 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 94% — put it in C minor, a key signature of 3 flats. The tempo printed above is the median of the 162 readings; 31% of them land within 2% of it, and the middle eight tenths of them run from 126 to 150 BPM.

At 129 BPM one beat lasts 465.1 milliseconds, so a sixteenth note is 116.3 ms and a dotted eighth 348.8 ms — the delay times for this recording. Counted half as fast it is 64.5 BPM, counted twice as fast 258. 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 13.77 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 0.22 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.

10 other recordings here are in C minor; the ones listed below are the closest in tempo.
