On/Off

230 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 84% — put it in G minor, a key signature of 2 flats. The tempo printed above is the median of the 230 readings; 10% of them land within 2% of it, and the middle eight tenths of them run from 83.4 to 99.2 BPM. That is a recording the detector cannot settle on — the readings are spread far enough that the median is a summary of a disagreement rather than a measurement anybody should trust to the decimal.

At 85.7 BPM one beat lasts 700.1 milliseconds, so a sixteenth note is 175 ms and a dotted eighth 525.1 ms — the delay times for this recording. Counted half as fast it is 42.9 BPM, counted twice as fast 171.4. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 446.4 Hz, which is 25 cents above concert A at 440 Hz — the sort of drift a tape machine or a slightly different mastering leaves behind. That is a fact about this transfer of the music, not about how it was played.

The dynamic complexity of the recording measures 5.83 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 0.885 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
