typedef struct fax_modems_state_s fax_modems_state_t |
The set of modems needed for FAX, plus the auxilliary stuff, like tone generation.
SPAN_DECLARE_NONSTD | ( | int | ) |
Get the next bit of data from a T.38 rate adapting non-ECM buffer context.
Apply T.30 receive processing to a block of audio samples.
s | The FAX context. | |
amp | The audio sample buffer. | |
len | The number of samples in the buffer. |
