A variable controlling speed/quality tradeoff of audio resampling.
Defined in SDL_hints.h
#define SDL_HINT_AUDIO_RESAMPLING_MODE "SDL_AUDIO_RESAMPLING_MODE"
If available, SDL can use libsamplerate ( http://www.mega-nerd.com/SRC/ ) to handle audio resampling. There are different resampling modes available that produce different levels of quality, using more CPU.
If this hint isn't specified to a valid setting, or libsamplerate isn't available, SDL will use the default, internal resampling algorithm.
As of SDL 2.26, SDL_ConvertAudio() respects this hint when libsamplerate is available.
This hint is currently only checked at audio subsystem initialization.
This variable can be set to the following values:
