Data Structures
struct	dsp16_resampling_options_t
	Options to attribute to the resampling algorithm. More...
struct	dsp_resampling_context_t
	This structure is used to store the context of streaming information during resampling process. More...
struct	dsp_resampling_t
	This structure is used to store the context of a resampling process. More...

Functions
void	dsp16_resampling_compute (dsp_resampling_t *dsp_resampling, dsp16_t *output, dsp16_t *input, int channel)
	The re-sampling computation function. More...
int	dsp16_resampling_get_output_current_buffer_size (dsp_resampling_t *dsp_resampling)
	Returns the current length in sample of the output signal. More...
int	dsp16_resampling_get_output_max_buffer_size (dsp_resampling_t *dsp_resampling)
	Returns the maximal length in sample of the output signal. More...
bool	dsp16_resampling_link (dsp_resampling_t *dsp_resampling_output, dsp_resampling_t *dsp_resampling_input)
	Link a stream previously re-sampled using the dsp_resampling_input resampling structure with the new re-sampling structure dsp_resampling_output. This is used to keep the continuity with two pieces of a stream re-sampled using two different re-sampling parameters. More...

Resampling setup function
typedef void *(*	malloc_fct_t )(int)
	A pointer on a memory allocation function. More...
typedef void(*	free_fct_t )(void *)
	A pointer on a memory free function. More...
dsp_resampling_t *	dsp16_resampling_setup (int input_sample_rate, int output_sample_rate, int buffer_size, int order, int nb_channels, malloc_fct_t malloc_fct, dsp16_resampling_options_t *options)
	This function is the 16-bit signal resampling setup function. It has to be called only once at the initialization of the resampling process. More...
void	dsp16_resampling_free (dsp_resampling_t *dsp_resampling, free_fct_t free_fct)
	Function used to free the previously allocated structure issued by the dsp16_resampling_setup function. More...
