Functions
std::pair< int16_t, int16_t >	itpp::ulaw_range ()
	G.711 u-Law compressor input range. Returns (min,max) input values in std::pair.
uint8_t	itpp::ulaw_compress (int16_t s)
	G.711 u-Law compression function. Returns encoded value for sample s.
int16_t	itpp::ulaw_expand (uint8_t s)
	G.711 u-Law expansion function. Returns decoded value for previously compressed sample s.Expansion is performed by the table look up.
std::pair< int16_t, int16_t >	itpp::alaw_range ()
	G.711 a-Law compressor input range. Returns (min,max) input values in std::pair.
uint8_t	itpp::alaw_compress (int16_t s)
	G.711 a-Law compression function. Returns encoded value for sample s.
int16_t	itpp::alaw_expand (uint8_t s)
	G.711 u-Law expansion function. Returns decoded value for previously compressed sample s.Expansion is performed by the table look up.
