Good Times Bad Times

162 independent analyses of this recording were submitted to AcousticBrainz. Most of them — 94% — put it in A major, a key signature of 3 sharps. The tempo printed above is the median of the 162 readings; 59% of them land within 2% of it, and the middle eight tenths of them run from 94.2 to 184.6 BPM.

At 184.6 BPM one beat lasts 325 milliseconds, so a sixteenth note is 81.3 ms and a dotted eighth 243.8 ms — the delay times for this recording. Counted half as fast it is 92.3 BPM, counted twice as fast 369.2. A score would mark that Presto, by the ranges this site uses.

The analyses put the reference pitch of the recording at 439.4 Hz, which is 2.5 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 4.7 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 0.908 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
