Detailed Description

SDL_libretro - audio subsystem.

Uses SDL3's push model. The device stream is opened with a NULL callback and samples are pushed directly via SDL_PutAudioStreamData().

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.
