Boadicea

178 independent analyses of this recording were submitted to AcousticBrainz. All but a handful of them — 97% — put it in C minor, a key signature of 3 flats. The tempo printed above is the median of the 178 readings; 96% of them land within 2% of it, and they barely differ at all.

At 101.4 BPM one beat lasts 591.7 milliseconds, so a sixteenth note is 147.9 ms and a dotted eighth 443.8 ms — the delay times for this recording. Counted half as fast it is 50.7 BPM, counted twice as fast 202.8. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 443.3 Hz, which is 13 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 7.01 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 0.53 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
