###### (This function is part of SDL_mixer, a separate library from SDL.) # MIX_Mixer An opaque object that represents a mixer. ## Header File Defined in [](https://github.com/libsdl-org/SDL_mixer/blob/main/include/SDL3_mixer/SDL_mixer.h) ## Syntax ```c typedef struct MIX_Mixer MIX_Mixer; ``` ## Remarks The [MIX_Mixer](MIX_Mixer) is the toplevel object for this library. To use SDL_mixer, you must have at least one, but are allowed to have several. Each mixer is responsible for generating a single output stream of mixed audio, usually to an audio device for realtime playback. Mixers are either created to feed an audio device (through [MIX_CreateMixerDevice](MIX_CreateMixerDevice)()), or to generate audio to a buffer in memory, where it can be used for anything (through [MIX_CreateMixer](MIX_CreateMixer)()). ## Version This datatype is available since SDL_mixer 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIDatatype](CategoryAPIDatatype), [CategorySDLMixer](CategorySDLMixer)
