Meltdown

184 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 78% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 184 readings; 78% of them land within 2% of it, and the middle eight tenths of them run from 99.5 to 112 BPM.

At 111.9 BPM one beat lasts 536.2 milliseconds, so a sixteenth note is 134 ms and a dotted eighth 402.1 ms — the delay times for this recording. Counted half as fast it is 56 BPM, counted twice as fast 223.8. A score would mark that Moderato, by the ranges this site uses.

The analyses put the reference pitch of the recording at 441.3 Hz, which is 5 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 3.12 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 0.922 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
