AudioEffectSpectrumAnalyzer

    Audio effect that can be used for real-time audio visualizations.

    This audio effect does not affect sound output, but can be used for real-time audio visualizations.

    See also for procedurally generating sounds.

    enum FFT_Size:

    • FFT_SIZE_256 = 0 —- Use a buffer of 256 samples for the Fast Fourier transform. Lowest latency, but least stable over time.

    • FFT_SIZE_512 = 1 —- Use a buffer of 512 samples for the Fast Fourier transform. Low latency, but less stable over time.

    • FFT_SIZE_2048 = 3 —- Use a buffer of 2048 samples for the Fast Fourier transform. High latency, but stable over time.

    • FFT_SIZE_4096 = 4 —- Use a buffer of 4096 samples for the Fast Fourier transform. Highest latency, but most stable over time.

    • FFT_SIZE_MAX = 5 —- Represents the size of the enum.

    • buffer_length

    The size of the Fast Fourier transform buffer. Higher values smooth out the spectrum analysis over time, but have greater latency. The effects of this higher latency are especially noticeable with sudden amplitude changes.
