NAME¶

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

SYNOPSIS¶

#include <SDL3/SDL_audio.h>

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

DESCRIPTION¶

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.

MACRO PARAMETERS¶

x

an SDL_AudioSpec to query.

RETURN VALUE¶

Returns the number of bytes used per sample frame.

THREAD SAFETY¶

It is safe to call this macro from any thread.

AVAILABILITY¶

This macro is available since SDL 3.2.0.
