SDL_SetAudioStreamFrequencyRatio - Change the frequency ratio of an audio stream.
Defined in SDL3/SDL_audio.h
#include "SDL3/SDL.h"
bool SDL_SetAudioStreamFrequencyRatio(SDL_AudioStream *stream, float ratio);
The frequency ratio is used to adjust the rate at which input data is consumed. Changing this effectively modifies the speed and pitch of the audio. A value greater than 1.0 will play the audio faster, and at a higher pitch. A value less than 1.0 will play the audio slower, and at a lower pitch.
This is applied during SDL_GetAudioStreamData , and can be continuously changed to create various effects.
Returns true on success or false on failure; call
SDL_GetError () for more information.
It is safe to call this function from any thread, as it holds a stream-specific mutex while running.
This function is available since SDL 3.2.0.
