Struct sdl2_sys::SDL_AudioSpec [−][src]
#[repr(C)]pub struct SDL_AudioSpec { pub freq: c_int, pub format: SDL_AudioFormat, pub channels: Uint8, pub silence: Uint8, pub samples: Uint16, pub padding: Uint16, pub size: Uint32, pub callback: SDL_AudioCallback, pub userdata: *mut c_void, }
The calculated values in this structure are calculated by SDL_OpenAudio().
For multi-channel audio, the default SDL channel mapping is: 2: FL FR (stereo) 3: FL FR LFE (2.1 surround) 4: FL FR BL BR (quad) 5: FL FR FC BL BR (quad + center) 6: FL FR FC LFE SL SR (5.1 surround - last two can also be BL BR) 7: FL FR FC LFE BC SL SR (6.1 surround) 8: FL FR FC LFE BL BR SL SR (7.1 surround)
Fields
freq: c_int
< DSP frequency – samples per second
format: SDL_AudioFormat
< Audio data format
channels: Uint8
< Number of channels: 1 mono, 2 stereo
silence: Uint8
< Audio buffer silence value (calculated)
samples: Uint16
< Audio buffer size in sample FRAMES (total samples divided by channel count)
padding: Uint16
< Necessary for some compile environments
size: Uint32
< Audio buffer size in bytes (calculated)
callback: SDL_AudioCallback
< Callback that feeds the audio device (NULL to use SDL_QueueAudio()).
userdata: *mut c_void
< Userdata passed to callback (ignored for NULL callbacks).
