DESCRIPTION
The SDL_AudioSpec structure is used to describe the format of some audio data. This structure is used by SDL_OpenAudio and SDL_LoadWAV. While all fields are used by SDL_OpenAudio only freq, format, samples and channels are used by SDL_LoadWAV. We will detail these common members here.
|
freq |
The number of samples sent to the sound device every second. Common values are 11025, 22050 and 44100. The higher the better. | ||
|
format |
Specifies the size and type of each sample element | ||
|
AUDIO_U8 |
|||
|
AUDIO_S8 |
AUDIO_U16 or
AUDIO_U16LSB
AUDIO_S16 or AUDIO_S16LSB
AUDIO_U16MSB
AUDIO_S16MSB
AUDIO_U16SYS
AUDIO_S16SYS
|
channels |
The number of seperate sound channels. 1 is mono (single channel), 2 is stereo (dual channel). | ||
|
samples |
When used with SDL_OpenAudio this refers to the size of the audio buffer in samples. A sample a chunk of audio data of the size specified in format mulitplied by the number of channels. When the SDL_AudioSpec is used with SDL_LoadWAV samples is set to 4096. |
