Struct fermium::audio::SDL_AudioCVT [−][src]
A structure to hold a set of audio conversion filters and buffers.
Note that various parts of the conversion pipeline can take advantage of SIMD operations (like SSE2, for example). SDL_AudioCVT doesn’t require you to pass it aligned data, but can possibly run much faster if you set both its (buf) field to a pointer that is aligned to 16 bytes, and its (len) field to something that’s a multiple of 16, if possible.
Fields
needed: c_int
Set to 1 if conversion possible
src_format: SDL_AudioFormat
Source audio format
dst_format: SDL_AudioFormat
Target audio format
rate_incr: f64
Rate conversion increment
buf: *mut u8
Buffer to hold entire audio data
len: c_int
Length of original audio buffer
len_cvt: c_int
Length of converted audio buffer
len_mult: c_int
buffer must be len*len_mult big
len_ratio: f64
Given len, final size is len*len_ratio
filters: [SDL_AudioFilter; 10]
NULL-terminated list of filter functions
filter_index: c_int
Current audio conversion function
