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_tdsp16_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...
