       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.

RETURN VALUE
