Disco Heaven

129 independent analyses of this recording were submitted to AcousticBrainz. Fewer than half of them — 48% — put it in C major, a key signature of no sharps and no flats. The tempo printed above is the median of the 129 readings; 100% of them land within 2% of it, and they barely differ at all.

At 128.1 BPM one beat lasts 468.4 milliseconds, so a sixteenth note is 117.1 ms and a dotted eighth 351.3 ms — the delay times for this recording. Counted half as fast it is 64.1 BPM, counted twice as fast 256.2. A score would mark that Allegro, 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 3.56 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 0.962 on Essentia's 0-to-1 scale, which is not decibels and is not comparable to a streaming service's number.
