AudioEffectPitchShift¶
Inherits: AudioEffect < Resource < Reference < Object
Añade un efecto de audio de cambio de tono a un bus de Audio.
Sube o baja el tono del sonido original.
Descripción¶
Permite la modulación del tono independientemente del tempo. Todas las frecuencias pueden ser aumentadas/disminuidas con un efecto mínimo en los transitorios.

Enumeraciones¶
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_1024 = 2 --- Use a buffer of 1024 samples for the Fast Fourier transform. This is a compromise between latency and stability 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 --- Representa el tamaño del enum FFT_Size.
Descripciones de Propiedades¶
FFT_Size fft_size
Default |
|
Setter |
set_fft_size(value) |
Getter |
get_fft_size() |
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.
int oversampling
Default |
|
Setter |
set_oversampling(value) |
Getter |
get_oversampling() |
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.
float pitch_scale
Default |
|
Setter |
set_pitch_scale(value) |
Getter |
get_pitch_scale() |
The pitch scale to use. 1.0 is the default pitch and plays sounds unaltered. pitch_scale can range from 0.0 (infinitely low pitch, inaudible) to 16 (16 times higher than the initial pitch).
