Convert some audio data of one format to another format.
int SDL_ConvertAudioSamples(const SDL_AudioSpec *src_spec, const Uint8 *src_data, int src_len, const SDL_AudioSpec *dst_spec, Uint8 **dst_data,int *dst_len);
|src_spec||The format details of the input audio|
|src_data||The audio data to be converted|
|src_len||The len of src_data|
|dst_spec||The format details of the output audio|
|dst_data||Will be filled with a pointer to converted audio data, which should be freed with SDL_free(). On error, it will be NULL.|
|dst_len||Will be filled with the len of dst_data|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Please note that this function is for convenience, but should not be used to resample audio in blocks, as it will introduce audio artifacts on the boundaries. You should only use this function if you are converting audio data in its entirety in one call. If you want to convert audio in smaller chunks, use an SDL_AudioStream, which is designed for this situation.
Internally, this function creates and destroys an SDL_AudioStream on each use, so it's also less efficient than using one directly, if you need to convert multiple times.
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
