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

-- | Define an SDL_AudioFormat value.
--
--     The SDL_DEFINE_AUDIO_FORMAT macro as a function. SDL does not support custom audio formats, so this is not of much use externally, but it can be illustrative as to what the various bits of an SDL_AudioFormat mean. For example, SDL_AUDIO_S32LE is signed, littleendian, integer, 32 bits.
