SDL_AudioFormat

Audio format flags.

Header File

Defined in SDL_audio.h

Syntax

typedef Uint16 SDL_AudioFormat;

Remarks

These are what the 16 bits in SDL_AudioFormat currently mean... (Unspecified bits are always zero).

++-----------------------sample is signed if set
||
||       ++-----------sample is bigendian if set
||       ||
||       ||          ++---sample is float if set
||       ||          ||
||       ||          || +---sample bit size---+
||       ||          || |                     |
15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00

There are macros in SDL 2.0 and later to query these bits.

Code Examples

extern SDL_AudioFormat fmt;
if (SDL_AUDIO_ISFLOAT(fmt)) {
    printf("floating point data\n");
} else {
    printf("integer data\n");
}
printf("%d bits per sample\n", (int) SDL_AUDIO_BITSIZE(fmt));
