SINES Tools: Harmonic Tension Analyzer

1. Click on "Start" to set all values on default.
2. Upload an mp3 or wav audio file.
3. Click on "Analyse"
4. optional: Use the sliders to set the boundary between chord and note detection (Single Note Dominance: low values: individual notes are
    detected, high values: chords are recognized), to set the complexity of chord recognition (Complexity Threshold: the higher the values, the
    more complex chords are recognized), and to smooth the calculated harmonic tension curve (the higher the values, the smoother the curve).
5. optional: View the chromagram and harmonic tension curve and play the detected chords with the Play chords button.
6. Click on "Show JS Arrays" to view the harmonic (tension) data as Javascript arrays or click on "Export CSV" to export them as a CSV/Excel file.
