Desecration Smile

161 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 75% — put it in A minor, a key signature of no sharps and no flats. The tempo printed above is the median of the 161 readings; 83% of them land within 2% of it, and the middle eight tenths of them run from 92 to 117.2 BPM.

At 92.1 BPM one beat lasts 651.5 milliseconds, so a sixteenth note is 162.9 ms and a dotted eighth 488.6 ms — the delay times for this recording. Counted half as fast it is 46.1 BPM, counted twice as fast 184.2. 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 3.37 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 0.832 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
