The Guns of Brixton

197 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 96% — put it in B minor, a key signature of 2 sharps. The tempo printed above is the median of the 197 readings; 91% of them land within 2% of it, and the middle eight tenths of them run from 95.5 to 96.6 BPM.

At 96.5 BPM one beat lasts 621.8 milliseconds, so a sixteenth note is 155.4 ms and a dotted eighth 466.3 ms — the delay times for this recording. Counted half as fast it is 48.3 BPM, counted twice as fast 193. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 439.5 Hz, which is 2 cents below 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 4.19 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 0.941 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
