    FNV24: [9F7CX]

    Cases

    • case fftSize256

      Use a buffer of 256 samples for the Fast Fourier transform. Lowest latency, but least stable over time.

    • case fftSize512

      Use a buffer of 512 samples for the Fast Fourier transform. Low latency, but less stable over time.

    • case fftSize1024

      Use a buffer of 1024 samples for the Fast Fourier transform. This is a compromise between latency and stability over time.

    • case fftSize2048

      Use a buffer of 2048 samples for the Fast Fourier transform. High latency, but stable over time.

    • case fftSize4096

      Use a buffer of 4096 samples for the Fast Fourier transform. Highest latency, but most stable over time.

    • case max

      Represents the size of the FFTSize enum.

    • var fftSize: AudioEffectPitchShift.FFTSize

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

    • var oversampling: Int32

      The oversampling factor to use. Higher values result in better quality, but are more demanding on the CPU and may cause audio cracking if the CPU can’t keep up.

    • var pitchScale: Double

      The pitch scale to use. 1.0 is the default pitch and plays sounds unaffected. pitchScale can range from 0.0 (infinitely low pitch, inaudible) to 16 (16 times higher than the initial pitch).
