    • getVolume

      public float getVolume(int band)
      Returns the normalized volume (0 to 1) of a logarithmic frequency band. This only works after calling fft.logAverages(22, 3), which splits the audible range into ~30 musically spaced bands.
      Parameters:
      band - the log band index (0 = low bass, up to ~29 = high treble)
      Returns:
      normalized volume between 0 and 1 for that band

    • getVolume

      public float getVolume()
      Returns the overall normalized volume (0 to 1) across all frequency bands. This gives you a single value representing the "energy" of the current sound.
      Returns:
      average normalized volume across all log frequency bands
