Heart of Gold

362 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 84% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 362 readings; 79% of them land within 2% of it, and the middle eight tenths of them run from 85.1 to 172.3 BPM.

At 85.3 BPM one beat lasts 703.4 milliseconds, so a sixteenth note is 175.8 ms and a dotted eighth 527.5 ms — the delay times for this recording. Counted half as fast it is 42.7 BPM, counted twice as fast 170.6. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 440 Hz, which is 0 cents above 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 4.57 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 0.651 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
