[SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_HINT_AUDIO_FORMAT A variable controlling the default audio format. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_AUDIO_FORMAT "SDL_AUDIO_FORMAT" ``` ## Remarks If the application doesn't specify the audio format when opening the device, this hint can be used to specify a default format that will be used. The variable can be set to the following values: - "U8": Unsigned 8-bit audio - "S8": Signed 8-bit audio - "S16LE": Signed 16-bit little-endian audio - "S16BE": Signed 16-bit big-endian audio - "S16": Signed 16-bit native-endian audio (default) - "S32LE": Signed 32-bit little-endian audio - "S32BE": Signed 32-bit big-endian audio - "S32": Signed 32-bit native-endian audio - "F32LE": Floating point little-endian audio - "F32BE": Floating point big-endian audio - "F32": Floating point native-endian audio This hint should be set before an audio device is opened. ## Version This hint is available since SDL 3.1.3. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
