Bark at the Moon

168 independent analyses of this recording were submitted to AcousticBrainz. A bare majority of them — 59% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 168 readings; 92% of them land within 2% of it, and the middle eight tenths of them run from 146.3 to 147.9 BPM.

At 146.5 BPM one beat lasts 409.6 milliseconds, so a sixteenth note is 102.4 ms and a dotted eighth 307.2 ms — the delay times for this recording. Counted half as fast it is 73.3 BPM, counted twice as fast 293. A score would mark that Allegro, by the ranges this site uses.

The analyses put the reference pitch of the recording at 434.2 Hz, which is 23 cents below 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 2.27 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 0.925 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
