Change the input and output formats of an audio stream.
Defined in <SDL3/SDL_audio.h>
bool SDL_SetAudioStreamFormat(SDL_AudioStream *stream, const SDL_AudioSpec *src_spec, const SDL_AudioSpec *dst_spec);
SDL_AudioStream * | stream | the stream the format is being changed. |
const SDL_AudioSpec * | src_spec | the new format of the audio input; if NULL, it is not changed. |
const SDL_AudioSpec * | dst_spec | the new format of the audio output; if NULL, it is not changed. |
(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
Future calls to and SDL_GetAudioStreamAvailable and SDL_GetAudioStreamData will reflect the new format, and future calls to SDL_PutAudioStreamData must provide data in the new input formats.
Data that was previously queued in the stream will still be operated on in the format that was current when it was added, which is to say you can put the end of a sound file in one format to a stream, change formats for the next sound file, and start putting that new data while the previous sound file is still queued, and everything will still play back correctly.
It is safe to call this function from any thread, as it holds a stream-specific mutex while running.
This function is available since SDL 3.0.0.
