A variable controlling how the size of the RIFF chunk affects the loading of a WAVE file.

Header File

Defined in <SDL3/SDL_hints.h>




The size of the RIFF chunk (which includes all the sub-chunks of the WAVE file) is not always reliable. In case the size is wrong, it's possible to just ignore it and step through the chunks until a fixed limit is reached.

Note that files that have trailing data unrelated to the WAVE file or corrupt files may slow down the loading process without a reliable boundary. By default, SDL stops after 10000 chunks to prevent wasting time. Use the environment variable SDL_WAVE_CHUNK_LIMIT to adjust this value.

The variable can be set to the following values:

This hint should be set before calling SDL_LoadWAV() or SDL_LoadWAV_IO()


This hint is available since SDL 3.0.0.
