(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_AUDIO_FRAMESIZE

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

Header File

Defined in <SDL3/SDL_audio.h>

Syntax

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

Macro Parameters

x	an SDL_AudioSpec to query.

Return Value

Returns the number of bytes used per sample frame.

Remarks

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.
