SDL_AUDIO_FRAMESIZE

Calculate the size of each audio frame (in bytes) from an SDL_AudioSpec.

Header File

#define SDL_AUDIO_FRAMESIZE(x) (((unsigned int)SDL_AUDIO_BYTESIZE((x).format)) * ((unsigned int)((x).channels)))

x	an SDL_AudioSpec to query.

Returns the number of bytes used per sample frame.

This reports on the size of an audio sample frame: stereo Sint16 data (2 channels of 2 bytes each) would be 4 bytes per frame, for example.

This casts the value to unsigned int to avoid implicit sign conversion.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
