SDL_HINT_AUDIO_FORMAT - A variable controlling the default audio format.

Defined in SDL3/SDL_hints.h

#include "SDL3/SDL.h"

#define SDL_HINT_AUDIO_FORMAT SDL_AUDIO_FORMAT"

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.

This hint is available since SDL 3.2.0.
