All You Need Is Love

499 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 94% — put it in G major, a key signature of 1 sharp. The tempo printed above is the median of the 499 readings; 97% of them land within 2% of it, and the middle eight tenths of them run from 103.3 to 104.7 BPM.

At 104.5 BPM one beat lasts 574.2 milliseconds, so a sixteenth note is 143.5 ms and a dotted eighth 430.6 ms — the delay times for this recording. Counted half as fast it is 52.3 BPM, counted twice as fast 209. A score would mark that Andante, by the ranges this site uses.

The analyses put the reference pitch of the recording at 441.8 Hz, which is 7 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 5.3 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 0.805 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
