SDL_LoadWAV

Loads a WAV from a file path.

Header File

Syntax

bool SDL_LoadWAV(const char *path, SDL_AudioSpec *spec, Uint8 **audio_buf, Uint32 *audio_len);

Function Parameters

const char *	path	the file path of the WAV file to open.
SDL_AudioSpec *	spec	a pointer to an SDL_AudioSpec that will be set to the WAVE data's format details on successful return.
Uint8 **	audio_buf	a pointer filled with the audio data, allocated by the function.
Uint32 *	audio_len	a pointer filled with the length of the audio data buffer in bytes.

Return Value

(bool) Returns true on success. audio_buf will be filled with a pointer to an allocated buffer containing the audio data, and audio_len is filled with the length of that audio buffer in bytes.

This function returns false if the .WAV file cannot be opened, uses an unknown data format, or is corrupt; call SDL_GetError() for more information.

When the application is done with the data returned in audio_buf, it should call SDL_free() to dispose of it.

Remarks

This is a convenience function that is effectively the same as:

SDL_LoadWAV_IO(SDL_IOFromFile(path, "rb"), true, spec, audio_buf, audio_len);

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.1.3.
