SDL_SetAudioStreamGain - Change the gain of an audio stream.
Defined in SDL3/SDL_audio.h
#include "SDL3/SDL.h"
bool SDL_SetAudioStreamGain(SDL_AudioStream *stream, float gain);
The gain of a stream is its volume; a larger gain means a louder output, with a gain of zero being silence.
Audio streams default to a gain of 1.0f (no change in output).
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.
