Audio format flags.
Defined in SDL_audio.h
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.
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));
