SDL_SetAudioStreamGain(3) | SDL3 FUNCTIONS | SDL_SetAudioStreamGain(3) |
NAME¶
SDL_SetAudioStreamGain - Change the gain of an audio stream.
SYNOPSIS¶
#include <SDL3/SDL_audio.h>
bool SDL_SetAudioStreamGain(SDL_AudioStream *stream, float gain);
DESCRIPTION¶
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.
