Macros
#define	SDL_LIBRETRO_AUDIO_DEFAULT_LATENCY_MS   100
	The threshold of audio latency in milliseconds.
#define	SDL_LIBRETRO_AUDIO_DEFAULT_SAMPLE_RATE   48000
	Fallback rate used when a core reports no audio sample rate (<= 0).
#define	SDL_LIBRETRO_AUDIO_DRC_MAX_DELTA   0.005
	The amount to push the DRC to correct audio pitch.
#define	SDL_LIBRETRO_MIC_DEFAULT_RATE   44100

Functions
unsigned	SDL_Libretro_GetAudioLatency (const SDL_Libretro *lr)
	Get the minimum audio latency for the audio stream.
double	SDL_Libretro_GetSampleRate (const SDL_Libretro *lr)
	Get the audio sample rate the loaded core outputs at.
void	SDL_Libretro_SetAudioLatency (SDL_Libretro *lr, unsigned latencyMs)
	Set the desired minimum audio latency for the audio stream.

Detailed Description

SDL_libretro - audio subsystem.

Pushes libretro's S16 stereo samples directly to SDL3 via SDL_PutAudioStreamData(). SDL handles the format conversion and volume gain.

SDL_LIBRETRO_AUDIO_DRC_MAX_DELTA

#define SDL_LIBRETRO_AUDIO_DRC_MAX_DELTA   0.005

The amount to push the DRC to correct audio pitch.

The default is good for general use smoothing. Increase when expecting stutter.
